My sites have got 500 Error for almost 12 hours,only the sites on a FTP Server.
But 2 blogs on this FTP run well,thats' very strange.
dupola.com got 500 Error,beta.dupola.com run well,they are on a same FTP Server,but not the same MySQL server.
Then,I switch the two Database of them, dupola.com can run well with beta.dupola.com's MySQL Database.
But beta.dupola.com got 500 Error with dupola.com's Database.
Also,dupola.com/bbs is run well,it use the same Database as dupola.com
When I export my database to a zip or gzip file in phpMyAdmin,it got 500 Error too.
That's very strange,I submit a ticket to the Support Team,but they said this MySQL server is OK.The also said my scripts or softwares led this problem.
I checked my software,disable all plugins I am using,but it still got 500 Error.
These sites were running very good recently,just since yesterday.
Anyone know why?
