= Dolphin 7 Troubleshooter = If your web-server complies with [wiki:DolTech Dolphin Hosting Requirements] and you carefully followed al the steps described in [wiki:DetailedInstall Dolphin 7 Installation Guide], your site should work just fine. In some (rare) cases, you may encounter a problem. In this document we gather the most common known issues and their possible solutions.[[BR]] ---- '''[#Iseeablankpageintheplaceofthepage.

If '''display_errors''' option is turned off, then just blank page appears. You need to check PHP error log file for the exact error, or enable '''display_errors''' PHP setting - then instead of blank page you will see the error message. You maybe will need to ask your hosting support to change this setting. The error message will give you some clues about the source of the problem. You can check your PHP setting in Dolphin Admin Panel > Tools > Host Tools > PHP Info ---- == My page comes out gibberish. When I look at the source I see a lot of '''''' tags. == If the '''''' tags are being sent to the browser, it means your ''PHP'' is not working properly. All ''PHP'' code is supposed to be executed before the server sends the resulting ''HTML'' to your web browser. Make sure your web server meets the [wiki:DolTech requirements] to run Dolphin, that ''PHP'' is installed and configured properly, or contact your hosting provider or system administrator for assistance. ---- == I've got "Internal error 500". == This is web-server error. You need to check web-server error log files for the exact error message, it will give you some clues about the source of the problem. You maybe need to ask web hosting support to check error log files for you, since it maybe that you have no access to these files. ---- == My security image doesn't show up on join form. == __For Dolphin 7.1.x:__ You need to generate your own [http://www.google.com/recaptcha reCaptcha] keys and enter them in Dolphin Admin Panel > Settings > Advanced Settings > Security __For Dolphin 7.0.x and older:__ Check if you have [http://www.boutell.com/gd/ GD library] installed and if it's compiled with ''Free Type fonts'' library. If GD library is not installed, you should install the latest version of [http://www.imagemagick.org ImageMagick] and disable '''Use GD library for image processing in '''Admin panel -> Settings -> Advanced Settings'''. ---- == My image/sound/video uploads don't work. == It maybe many reasons for this: * __Incorrect permission__ - check Admin Panel > Tools > Host Tools > Permissions tab, for correct permissions everywhere * __Upload limits__ - check Admin Panel > Tools > Host Tools > Audit tab, for '''post_max_size''' and '''upload_max_filesize''' settings * __FFmpeg problems for sounds and video__ - check for correct permissions for ffmpeg in Permission tab and ffmpeg output in Site setup > ffmpeg in Audit tab in Admin Panel > Tools > Host Tools ---- == Forum displays a blank page. == Check if ''PHP'' is compiled with '''XSLT''' support, it can be checked in Admin Panel > Tools > Host Tools > Audit and PHP info tabs. ---- == My Dolphin site shows 500 internal server error. == First, you need to investigate your webserver error log file, for the exact error message, but most common problems are listed below: 1) Try to remove the '''Options -!MultiViews''' from the file '''.htaccess'''. Also remove any '''php_value''' and '''php_admin_value''' instructions from it. 2) Another problem causing this may be incorrect permissions on some files or folders. All folders should have 755 permissions, and all files should have 644 permissions (except for '''flash/modules/global/app/ffmpeg.exe''' which should have 755 permissions). 3) All Dolphin files and folders should have your FTP user as their owner. If it is not so, this can be another reason of the problem. ---- == Some or all of my Flash apps keep on loading and do not work. == 1) This problem usually happens when there are writable permissions on folders and files when PHP is running in CGI mode. To check the mode your PHP is running in, log into your Dolphin's Admin Panel and then open the page '''administration/phpinfo.php'''. To fix it, you will need to set all folders permissions to 755 and all files to 644. The file '''flash/modules/global/app/ffmpeg.exe''' should be also set to 755. 2) This problem may also be caused by script's inability to open widgets' default skins. You can try the following tweak which will be harmless for the rest of the script functionality: open the file '''flash/modules/MODULE_NAME/skins/index.php and replace the line {{{ $sFile = $aResult['current'] . "." . $aResult['extension']; }}} with {{{ $sFile = "default.swf"; }}} You can also try to comment out these lines if you still experience the problem: {{{ /* - comment start require_once("../../../../inc/header.inc.php"); require_once($sIncPath . "functions.inc.php"); require_once($sIncPath . "apiFunctions.inc.php"); require_once($sIncPath . "xml.inc.php"); $aPathParts = explode("/", $_SERVER['PHP_SELF']); $iPartsCount = count($aPathParts); $aResult = getExtraFiles($aPathParts[$iPartsCount-3], $aPathParts[$iPartsCount-2]); comment end - */ }}} '''''MODULE_NAME''''' stands for '''board''', '''chat''', '''desktop''', '''im''', '''mp3''', '''photo''', '''video''' or '''video_comments'''. ---- == When I upload a video it always says "video is being processed". == 1) Check if the crons are installed and running properly. You can check your bug report email for messaged from the crons and if they contain any problem messages. 2) Check if ffmpeg.exe is executable and produces any output. This can be checked in ''Admin Panel -> Tools -> Host Tools -> Host Params'' 3) Your server may not support H264 codec and thus can't process videos. In this case, the codec should be disabled in "Admin Panel -> Modules -> Flash Apps -> Video Player -> Settings". ---- == Forum fails with this error message: [L[Site is unavailable]] == When you insert javascript on Dolphin pages, this may result in Dolphin native javascript breaking. To see what exactly is breaking the forum, you need to load the following URL in your browser: {{{ forum/?debug=1 }}} Usually, the problem is caused by these two lines inserted in some javascript ads and banners: {{{ // }}} So, search for these lines in your javascript code and remove them. ---- == I have installed/created a new template for Dolphin and the Forum stopped to work. == When you create or install a new template, you should consider that the same template should be created for the forum too. Templates for Orca Forum should be placed in the folder '''modules/boonex/forum/layout/''' where you can find your default template '''uni''' and the '''base''' folder whose settings all other templates will inherit. If you didn't create a template for Orca but you would like to use it with the default UNI template, you will need to tweak it: rename the '''uni''' folder to your custom template's name, for example, if your template's folder name is called '''tmpl_cucu''', rename the '''uni''' folder to '''cucu'''; go to the '''cucu''' folder and open the file '''params.php'''; rename all instances of the '''uni''' folder to '''cucu''' and save the file; now you only need to go to '''Admin Panel -> Modules -> Orca Forum -> Manage Forum''' and recompile your languages. ---- == I get "allowed memory size exhausted error". == This error comes from unsufficient PHP settings. I will show you how to change some PHP settings to prevent this kind of error and some other errors, too. 1) If PHP is running as an Apache module. Open the file ".htaccess" in Dolphin installation directory and add these at the very end of it: {{{ php_flag allow_url_include Off php_value upload_max_filesize 128M php_value post_max_size 256M php_value memory_limit 128M php_value max_input_time 3000 php_value max_execution_time 3000 php_flag magic_quotes_gpc Off php_flag short_open_tag On }}} 2) If PHP is running as CGI or FastCGI application. Open the file "php.ini" in Dolphin installation directory or create a new one. Add these lines at the very end of the file: {{{ magic_quotes_gpc = Off safe_mode = Off allow_url_include = Off allow_url_fopen = On register_globals = Off upload_max_filesize = 128M post_max_size = 256M memory_limit = 128M max_input_time = 3000 max_execution_time = 3000 short_open_tag = On }}} You need to place this file in every sub-directory of your Dolphin folder. This can be done by running the following command in your SSH shell: {{{ cd dolphin_dir find ./ -type d -exec cp php.ini {} \; rm -rf ./flash/modules/*/skins/php.ini ./flash/modules/*/langs/php.ini ./modules/boonex/forum/install/langs/php.ini ./modules/boonex/forum/integrations/base/langs/php.ini }}} '''dolphin_dir''' should be replaced by the full path to Dolphin directory, for example "/home/user/public_html/"
