White Screen after attempted upgrade

Hi @cloudchamber,

This is either linked with the Apache upgrade or your .htaccess file. Can you try by temporarily removing it? Also, I’d recommend you to check with your host in this regard.

Have a nice day ??

Can you list here what you attempted to update? i.e a plugin, a theme, or wordpress version or php? What did you updated? What did you updated from? Also please list your current hosting environment with their php parameters.

Hi Salan, I tried temporarily moving the .htaccess file and it didn’t help, unfortunately.
Kenneth, I attempted to upgrade to WordPress 5.5.1. I can’t remember exactly which version I had before but it was 5.something I am pretty sure, because usually update when prompted. I work through Host Papa and Cpanel and phpMyAdmin, through which I had to disable all plugins since I can’t reach my dashboard. (I tried updating WP at first through the dashboard, then tried manually as described in the documentation.)
With php there is something strange, when I set it to 7.2 I get the error message when trying to log in on my admin page: “There has been a critical error on your website. Please check your site admin email inbox for instructions.”, when I set it to 7.4 the error message doesn’t even show. For both versions 7.2 and 7.4, there is NO error message when I go to my site, just a white page, even though I have debugging enabled in my config:
define(‘WP_DEBUG’, true);
define( ‘WP_DEBUG_DISPLAY’, true );
And there is no message in the error log either.
Hope this gives you a better idea.
Best wishes, Helen

p.s. for what it’s worth, here is an anomaly from my error log, 99% of them are like the ones in my first post, but this one must have occurred when I tried to install the new version of WP manually. There is a new but empty “upgrades” folder in my wp-content file. I really hope someone can help get my site back up!

This issue seems to be related to you theme. Can you switch to a wp basic theme, i.e. 2020, 2019 etc. ?

It should have loaded at least the default theme. Anyway, everything just started working again, like magic. I didn’t do anything special since my post last night. Maybe it was in the end a matter of just being patient for the Apache upgrade like Salman said. Once the site started loading the default theme, I was able to get the 2020 theme rolling. Thanks everyone for your help!
