Hi there
I have a problem with two websites. I cannot update the plugins anymore because an error 500 appears.
I think the problem is caused by a plugin or maybe the old version of X both sites are using.
The first website uses wordpress 4.9.6 and x 4.3.0
The second site has wordpress and x 4.9.6 and x 4.2.2
I would like to solve the problem by
- Updating X
- Remove each plugin by ftp to see which one causes the problem.
These sites were created in 2014 and 2015 and by then there was no cornerstone plugin. So first I want to remove Cornerstone. Can I do this without the whole site will collapse?
As you can see, the version of X is also an old one. Why is that? There are no notifications about new versions, why not? Of course I validated X on both sites.
If I upload a new version and manually update X, could that give problems?
I hope you can help me and tell me what I can do best.
