Hi Camu,
Thank you for your offer, but it’s solved now. A lot of other plugins started to struggle as well, so I ended up contacting the support at ProPhoto again. After several hours I got this answer:
“Ok, I think it may have actually been a bug in the ProPhoto files. We ended up seeing a similar type issue the other day that got fixed in a ProPhoto update, so I replaced it (and WordPress just to be safe) and activated all of your plugins again and it seems to be working ok now. I’ve checked several times to see if it stops working again, like you and I saw, but so far, it’s still looking correct. So I hope that takes care of it. But if it disappears again, be sure to let me know! Thanks”
Sorry for this and thank you again for being willing to help me!
