I have a website that involves reviewing websites against certain criteria/features, etc.
To do this, many of my review posts have a custom metabox fields that lets me add the info to the post and re-use it across the site.
Since July, I've been unable to add any new criteria/features OR completely new Custom Fields. If I do, all my existing Custom Fields are removed - the whole lists just show blank entirely.
Support suggested I try changing the mbb_version number in the wp_options via PHPmyadmin - but this doesn't exist in my database, having checked.
Any suggestions? I haven't been able to add any info for ages!
