Hi folks this sounds like I have the right thread.
We are running OS CentOS Linux 7.9.2009 (Core). we have 2 domain on the host each domain has max 100 MB storage use so it's not heavy sites, 1 is working well, the other
https://turkeymedicals.com is giving the 500 error. As far as I know any 5XX is server side error.
1- Our hosting told to upgrade the 1 GB to 2 GB RAM, I see below memory limit to 1024MB. However still get the 500 error on the website, when we right click and oper few pages. The error seems to start after 5-6 pages are opening at the same time, so we took care of that part by disabling right click with a wordpress plugin. Th 500 also starts when we tweet a new post and few people click to open to read the post, at the same time maybe 10-12 people.
2- Hosting replied again this time told us it has to do with PHP version so we did that also to PHP support (PHP version 7.3.31) and run PHP as FASTCGI application served by Apache.
It has been few months past and annoying as we need the performance, we don not get any establishing database error at all.
3- Just again today hostng told us there is no problem accessing your website. Screenshot:
Screenshot and the error 500 is a software error, and if the error is repeated, we recommend that you activate the error display by the software and provide control.
We have been using Plesk for 1 year now and have 2 servers, and not the IT guru to change any settings or fix the issue, other than perforing a backup and download.
Any feedback from the pro's would be greatly appriciated. Plesk is up-to-date. Thanks a lot.
