I have been using MAMP Pro for many years. So far, updates have always worked flawlessly. However, the update from MAMP Pro 7.1.x → 7.2 displays this error message for all Kirby 4.5.0 projects, which unfortunately I cannot assign. Of course I cleared the cache and media folders. A fresh starter kit also displays this message.
The MAMP WebStart page is displayed without problems.
I can also access all Kirby projects with HERD.
Before I do a hardcore reset of MAMP, I prefer to ask here in the forum if the problem is known.
