WP Dashboard white screen – after switching to PHP 7

    Ok i have this “random” issue for a year and i tried to solve it on my own but i am unable to do it. I say random because on some websites on the same server this seems to work normally (????). Switching to PHP 7 is just fine.

    Description: website is working just fine. It is that after i switch from php 5.6 to php 7 in my web hosting panel – i can not access WP dashboard anymore. When trying to i get blank white screen. Note that website still work normally – i just can’t get access to WP Dashboard. After i switch back to PHP 5.6 my WP Dashboard can be accessed normally.

    I tried usual things such as .htaccess tuning but that did not had any impact. Tried to delete all plugins – no impact.

    To me it looks like every time i switch to PHP 7 (and i really need v7) i am getting problem accessing WP dashboard. And i am hitting a wall.

    Any suggestion? Where to start at least..

    Cheers!

  • Hello!

    Since you have already tried to deactivate all plugins etc ( if it was done properly ) the only thing left is to check your error logs to see if anything comes up in there that might give us a hint on what is causing the issue and be able to help further if possible.

    Since you have access on your hosting solution to change between PHP version, surely you’ll have access to logs as well.

    Usually it’s a plugin / theme code that runs only on the admin area that might be causing this but since you said you removed them then the only thing left would be to check the logs and try to pinpoint the problem as it’s very broad at the moment.

    Thank you for responding. Any particular log (it’s apache web server). But i wouldn’t count on it since actually web server is running fine and website is running fine just WP dashboard not..

    Btw i never did that (never needed it) but there is some WP debug option or possibility of worpdress to make log errors as well? Enabled through wp config?

    I am going to dive in WP documentation in the meantime and post here my findings if anyone else will have this problem so it can find this posting helpful..

    Found the culprit after i enabled WP debug through wp-conig.php

    it was wrong server configuration file (otherwise hidden) hidden in root folder.

    Thank you all.

    No problem!

    If you want to enable WP Debug you can do by editing your wp-config.php by following the instructions at

    Inform us of any errors that might throw some light and possibly lead to a solution to the problem !
