Is the admin bar enabled in his profile settings (Users > Your Profile)?
Have you tried:
– deactivating all plugins to see if this resolves the problem? If this works, re-activate the plugins one by one until you find the problematic plugin(s).
Try re-uploading all files & folders – except the wp-content folder – from a fresh download of WordPress.
Thanks. Already did that too, and no change.
Oddly, a log-out and log-in seems to sort it, so perhaps it was a cookie issue.
Hell, the whole thing’s so complex I’m surprised and glad it works as well as it does.
I also think it was a cookie issue. Glad you got it resolved.
Thanks. Yeah, I’m glad too – there’s a run of recent tech-stuff odd-happenings, beyond which i can explain as ‘my error’ which is tiring me.
