WordPress Speed Up Service | WordPress Website Maintenance Packages HTTP 500 Error on every page – nothing is helping!, by chembuddy Hello! I’m a beginner with wordpress and working with websites. I have crashed my main website page and the admin login pages as well. The error showing is a HTTP 500 error. I have tried every single troubleshooting available and nothing is working. This is what I was doing leading up to this. The wordpress version, plugins and a theme were out of date, so I updated these. I then received an error saying we had exhausted our memory! (there was 40MB available in total and using 1MB more was too much). This error would show up if I tried to search for new plugins, or install new plugins in wordpress, or even if I tried to revert back to an older version of wordpress! So I looked up online ways to increase the memory. I tried a few things but nothing worked. As I was changing a few things, the website decided to show the HTTP 500 error. I reverted everything back to how it was but it did not work. I left it until the next morning, where I realised I had left out a semi-colon in one of the php files. The website was fixed! No HTTP 500 error, just the same memory error from before. I left the website as it was, but now it is showing the same HTTP 500 error. All the files have been reverted back to how they were through backups, but it is still down. I have no idea how to proceed. If anyone has any idea of what I can do, please let me know! Thankyou very much. HTTP 500 Error on every page – nothing is helping!
