Error when enabling/disabling Integrations/apps

[Quints]

The integration still gets disabled/enabled but i get this error:

Error log:

ParseError: syntax error, unexpected '' (T_ENCAPSED_AND_WHITESPACE), expecting '-' or identifier (T_STRING) or variable (T_VARIABLE) or number (T_NUM_STRING) (0)

#5 community/system/Dispatcher/Dispatcher.php(110): IPS\Dispatcher\_Front->init()
#6 community/index.php(13): IPS\_Dispatcher::i()
#7 {main}

 

Also some other things that don't load anymore

 

I've noticed this happened after I uploaded a certain application, but after that i disabled and uninstalled it but the issues are still happening. How can I fix this?

 

thanks

What application was that? It looks to me like a case of strings not been properly formated/

There's your issue right there - use PHP7.4.x, 8.0.x or 8.1.x

I changed my PHP to 7.4 and it's solved. However if I change the PHP to 8.0 or 8.1 my forum crashes and all I see is an empty white page, is there any way to fix this?

Thanks!

Most likely one (or more) of your applications/plugins is not compatible with PHP 8. Check if there are any updates, if there aren't disable all modifications, switch to PHP 8, and then re-enable the modifications 1 by 1 checking which one is causing issues.

Or, you can just wait for version 4.7.2 to come out of beta since it contains a tool that can tell you which modifications won't work with PHP 8.

There is also the possibility that 8 and 8.1 do not have all the requirements for the platform to run. So it would be worth running the requirement checker while running those versions to check this
