I've been having some weird problems with one of my 2 blogs that I'm not having with the other and I'm not sure how to go about troubleshooting them.
Both are running 2.7.1, but one is failing in a number of processes while the other functions just fine. Both are on the same host server but use different databases.
For some time now (I can't say exactly when this started) my automated plugin updating has been broken. It gets to the point where it says that it's downloading the plugin, but then no browser activity takes place and nothing progresses beyond that point.
Automated WP upgrading also seems to be broken, I have no upgrade to perform right now but I've had to do the last couple iterations manually.
Those are annoying, but the REAL PROBLEM is this:
Every single time I post up a new entry, it posts just fine but I'm thrown to an Error 500 page:
"Error 500 - Internal server error
An internal server error has occured!
Please try again later."
This provides absolutely no useful debugging information, so I have no clue how to even take a wild guess as to where the problem might lie. Somewhere in my code? My plugins? My webserver? My database server? (My webhost was having server issues a little while back and I'm just assuming that they sorted them out 'cause I stopped getting the public errors across all my sites that were associated with that.)
Apparently quickposting doesn't trigger this error page, only full posting. Just realized that.
Furthermore, posting a comment just now gave me this error:
"Lost connection to MySQL server during query on line: 546"
Line 546 of.......??? Beats me.
So... anyone able to even tell me what questions I need to ask to start figuring this out?
