I can manage CSS just not good at coding PHP. I’ve looked but can’t work out which file and tag need to be customised.
I ended up unzipping my theme on my local machine, then uploading all the files via FTP while waiting for my hosting company to get back to me.
The Linux Admin at my hosting company has now fixed the problem, by setting every folders relevant to any theme uploads to 777.
Fixed! I unchecked a box in AWCPC.
It was one of the plugins.
I’m deactivating plugins and haven’t yet found the problem. Will try the other suggestions. Thanks.
