If you are still unable to access your site, open your DB table using phpmyadmin or a similar tool, go the the settings table and look for the following rows:
integrate_pre_include
integrate_bbc_codes
integrate_bbc_buttons
integrate_general_mod_settings
integrate_load_theme
And remove any string that starts with the prefix: OYTE_
This will completely uninstall the mod.
Please at least try and check the mod's content before filling a report. The mod
does give a warning regarding PHP compatibility:
if (version_compare(PHP_VERSION, '5.3.0', '<'))
exit('This mod needs PHP 5.3 or greater. You will not be able to install/use this mod, contact your host and ask for a php upgrade.');
These lines are taken straight from the mod's addHooks.php file. The mod is open source and its content is freely available for everyone to see at:
https://github.com/MissAllSunday/OharaYouTubeEmbed/tree/1.2The minimum required PHP version is visible listed on this mod's readme file too. The readme file is displayed every time you install this mod and it is the user's responsibility to fully read it before installing any mod.
If you have doubts about the mod's version and/or if it will be compatible with X PHP versions you should seek the mod's author for assistant
before proceeding with the installation or the PHP version change.
The reason why this check failed during your installation is simple, your PHP version cannot parsed the PHP file because this mod uses new functionality that your PHP version cannot handle. Unfortunately, using closures on PHP versions lower than 5.3 will make PHP crash, theres no solution for this except not using closures.
Your PHP version cannot handle closures, closures are a PHP > 5.3 thing and there is no fallback for previous versions meaning there is
absolutely nothing I can do to prevent this beyond adding a minimum required PHP version in the readme as well as a fallback PHP check and I already did those things.
BTW, any mod or any PHP script will have the same problem, even SMF itself. To check for the PHP version requires PHP itself, if PHP crashes, the check cannot be performed.
I did my fair share to tell the users about the minimum requirements and I'm sorry but it is
out of the scope of this mod to prevent user related errors. By user related errors I mean users neglecting to read the mod's readme file on install.
Lastly, no. Replacing the files with a backup isn't enough to solve this particular problem, this mod uses hooks which means most of the core functionality of this mod is completely separated from SMF's files. To completely remove the mod, besides replacing your files, the hooks this mod uses needs to be removed from your DB. You can do so by calling the file removeHooks.php via your browser but since you are unable to use PHP you need to do so manually following the instructions I gave previously.
Again, if you require assistant on how to completely remove a mod you should seek the mod's author for help.
