I was trying to fix a problem with the top menu and navigation menu not working on mobile devices. thanks to a friends suggestion, i found out it was the w3 total cache after deactivating plugins one at a time. I wanted to see if I could simply rollback the plugin instead of completely deactivating it so i used the wprollback to rollback to the previous version. I would do this and then check to see if the menu problem was resolved and then go back into plugins and roll it back to the one before that. I repeated the process but then the wp-admin page went blank and i couldn’t access anything in that nor the website itself. So I first checked to make sure the website wasnt down. i used https://downforeveryoneorjustme.com/rfidguard.ca and it said it was just me. so i cleared out the cookies, caches and saved images in chrome to try and refresh but it was obvious that the connection was too clogged to let us use it. my boss insisted that i keep working on it instead of simply waiting for our connection to the site to come back.
i started following some websites suggestions he told me to do including renaming the plugin folder in wp-content in the site directory to plugins.hold to deactivate the plugins. this did not work since we still couldn’t access the wp-admin. then i followed the video on this site: https://www.elegantthemes.com/blog/tips-tricks/how-to-fix-the-500-internal-server-error-on-your-wordpress-website
i started doing the first step he gave about renaming the .htaccess file to .htaccess.bak but i was unable to finish this step because i still was unable to access the wp-admin page. so i changed the name of the .htaccess file back. i continued with the video and did the WP_MEMORY_LIMIT and that didnt work, i then did a wordpress error log following these instructions: https://snapcreek.com/blog/wordpress-error-log-friend/
and in the error log it gave me this:
Fatal error: Uncaught Error: Call to undefined function mysql_escape_string() in /home/rfidguard/public_html/wp-content/themes/skimguard/functions.php:60 Stack trace: #0 /home/rfidguard/public_html/wp-settings.php(426): include() #1 /home/rfidguard/public_html/wp-config.php(100): require_once(‘/home/rfidguard…’) #2 /home/rfidguard/public_html/wp-load.php(37): require_once(‘/home/rfidguard…’) #3 /home/rfidguard/public_html/wp-login.php(12): require(‘/home/rfidguard…’) #4 {main} thrown in /home/rfidguard/public_html/wp-content/themes/skimguard/functions.php on line 60
i don’t know what to do with this. i have extremely limited programming experience so i’m honestly not sure what to fix. I know how to get to the line 60 that it’s talking about, but I don’t know what to do beyond that.
My boss had me do a restore from a backup made from even earlier in the cpanel. While it helped bring the Canadian site back up (even though it’s a mess), now the American .Co site is down. And we still can’t access the wp-admin for either sites. Please help!!
