All good on my sites again. I finished fixing the problems caused by the php upgrade on Coppermine installations on day before yesterday but wouldn’t you know – when I woke up yesterday, the Coppermine developers had rolled out a security upgrade while I slept *head desk* Talk about bad timing!
So again I had to re-upload all the Coppermine files to all my sites and re-install. Took me today and yesterday to finish but it’s all done now! So, all galleries on all sites should be up and working normally, and as far as I can tell, no content was lost 
If you encounter any problems, please do let me know, so I can fix them
