Website entirely unresponsive

Please note that your problem is no more urgent than anyone else’s.

Try checking your site’s error logs for messages. Your hosts should be able to help you in accessing your site’s error logs.

There’s nothing in my error log in cPanel

Try:
– switching to the default theme by renaming your current theme’s folder inside wp-content/themes and adding “-old” to the end of the folder name using FTP or whatever file management application your host provides.

– resetting the plugins folder by FTP or phpMyAdmin.

– re-uploading all files & folders – except the wp-content folder – from a fresh download of WordPress. Make sure that you delete the old copies of files & folder before uploading the new ones.

Phew!

Contacted my host who told me:
“MySQL has been restarted, the plugin started a locking query that caused a deadlock.”

All back now!
