I was in the midst deleting trash file and the internet connection is becoming really slow. When I clicked the Products tab in the wp-admin it says that: "Error establishing a database connection", although I did not change anything on the database. Also, there are times that the message: "Access to the webpage was denied" is appearing. I've restarted several times, and tried copying and pasting the link in different browsers, but its still appearing and I wonder why. Hope you guys can get me out of this stuff. I think I'm gonna broke down into pieces now. :(

verify that it's not an issue with your host. do you have command line or phpmyadmin access that can verify your database server is up? – Milo Jan 5 '12 at 5:18
no, i do not have any phpmyadmin access available and that's another problem. :( – Jivers Leuman Jan 5 '12 at 5:23
can you post a link to verify ? Unless your server is on a local machine (testing ) Starting and restarting will not help a DB error connection, nor does the browser matters . "Access to the webpage was denied" is another problem , but both appears to be a server problem, and not your browser or Personal Computer. – krembo99 Jan 5 '12 at 6:05
What host and hosting plan are you using? – Brian Fegter Jan 5 '12 at 6:18
i can't give you the direct link because as of now the errors are also appearing there. i was also thinking that the database might be edited or corrupted. – Jivers Leuman Jan 5 '12 at 6:23

Try logging into FTP and making sure there is no .maintenance file, also erase the upgrade folder. Its never a good idea to stop wordpress during an automatic update. Take a look at your wp-config file to make sure everything appears correct, it could of been editing it and you cut it off half way.

i just checked the FTP and it seems that the everything is correct in the wp-config file. Deleting the upgrade folder does not help since it do have any contents. Anyway, where can I find the .maintenance files? – Jivers Leuman Jan 6 '12 at 1:42
