I have a WordPress website in the development stage and I am having problems, I think it has something to do with the database. We recently combined 8 databases from the old site into one at the new site and since then, the site has been loading very very slow. Today I went to work on it some more and can't connect, either to the site itself or the Wordpress back end. I received an error saying the site could not establish a database connection. I also received the following error, if this helps.
"The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, firstname.lastname@example.org and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.
Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request."
I am not sure what is wrong and I need a Wordpress/Database expert that can diagnose and solve the problem quickly and effeciently. If you respond to this job posting, please be qualified in both Wordpress and Database Administration. Also, please quote me a fixed price or let me know approximately how many hours it might take to complete this job.
