• I update the wordpress from 5.2.2 to 5.8 today,(5.7.2 is also not working), it said it was updated successfully, however after it redirect the wordpress, it is crashing. the front-end page is showing”There has been a critical error on this website.”
    and the login/ admin page is not working, it show “redirected you too many times.” I check the message in Google Inspect, in the network, the status of wp-login.php is always 302 found.

    and I was searching the solution in Google, I tired everything in Google, adding a code “$_SERVER[‘HTTPS’]=’on’;” in wp-config.php, it works, but i can’t login the back-end via my account and password, it said “Sorry, you are not allowed to access this page.” , the status of wp-login.php is always 302 found and the status of sp-admin.php is 403 forbidden, and the front-end page is still not working.

    I have done .htaccess, clean cache and cookies, disable plugins. but they are not working in my case.
    what can I do?

    Errors like this are logged. Check the error log on your server. If you can’t find the log, please contact your host.

    Meantime, enable wp_debug and wp_debug_log and after an error, look at wp-content/debug.log to see if anything gets logged there. https://www.ads-software.com/support/article/debugging-in-wordpress/

    When you say you disabled plugins, did you do it by renaming the plugins directory under wp-content directory or some other way?

    @ashfame ok, I will try to turn on the wp-debug and find the log,

    about disabled the plugins, I have try turn off the plugins in CMS, rename the directory and do it both at the same time.

    Also, I just use the stupid way to update the wordpress from 5.2.2 to 5.2.12 / 5.3 / 5.4 / 5.8 manually, and find out it will happen some error when I move the new version wp-include file to the website, and it will crash again.

    I just thinking is that php version causing the problem? my php version is 7.3.2 for wordpress 5.2.2. It works perfectly. and I just saw the wordpress website is suggesting the minimum version of php is 7.4. but I can’t find out which php version is suitable for the old version of wordpress (5.2.12 / 5.3 / 5.4)

    You don’t want to run old WordPress versions for long, to ensure you are running fixes for all known issues (including security bugs).

    Also, there is no need to update WordPress incrementally manually. You can upgrade quite few installs by simply overwriting files from the latest release. Now of course if you have a code conflict of any kind, it is going to need resolution, which would happen with either approach.

    Logs will tell the exact problem that’s happening. Why do you wish to run older version of WordPress with an older PHP version, that might be potentially insecure or will be insecure in future?
