Hi Krishna

Do you find the same problem after reverting to Twenty Twelve theme?

sorry what is Twenty twelve theme?

I am unable to enter themes to edit

It could be for a lot of reasons. Have you tried Krishna’s advice and temporarily switched to the Twenty Twelve theme?

You are running a really outdated (as in many years old) commercial theme and that could the the cause of your problem.

Whoops. It’s much worse then that, you are running a really old version of WordPress. The current version is 3.5.1 (soon to be 3.6) and you are running 3.3.2.

You really want to consider doing the following. Read up on the below links and make sure you can restore from your backups just in case.

– Backup and keep somewhere safe your whole database and files.

– Switch to the Twenty Eleven theme

– Read up and try a manual upgrade in stages.

Once you’ve successfully come up to speed version-wise you’ll have a more supportable WordPress installation.

o.k thanks for this. It all sounds very complicated but I will try!

am I able to backup if I can’t access my site to edit it though?

Yes, you can backup by accessing your hosting control panel.

I have backup the site but unfortunately my site now longer shows on the web!
