[Solved] Upgrading to latest release resulting in HTTP Error 500 Internal server error

Hi  koris456,

Could you please deactivate all plugins and check again? 

Same big problem after updating wpDiscuz from 5.1.2 to 5.1.3. Error 500 and can't access to admin.

If I deactivate wpDiscuz by ftp, I can access again.

Please solve it as soon as possible!

Hi @catalizaweb,

Please provide us the error message in the log file.

I did this twice to be sure, went through ftp to rename the plugins folder and rename it back, then re-activated every plugin one by one to see what was causing it. It's this one. I've rolled back the updated to the previous version for now and it's fine, but that new version upon trying to update gives you an empty white page with only the HTTP Error 500 Internal server error message.

@koris456

Please leave the error message in the log file.

Hi @koris456,

Please update to latest wpDiscuz 5.1.4 version. Delete all error logs and check it again.

That did it. Thanks so much for the quick response!

Hi I send you the log by email.

Thanks.

Thank you catalizaweb,
