Extension still won’t work
Thanks for answering.
I tried this before, I already found this *.pdf on your website. The path in my library is a little different at the end, it goes the same until Dreamweaver CS4, then I have 3 folders: Common, de_DE and d en_US. The Common-Folder contains nothing. The other 2 folders contain both another folder named Configuration. They contain a lot of stuff. In the de_DE / Configuration-Folder is among other things a Document called MacFileCache-53340D12.dat and in the en_US / Configuration-Folder is also a Document called MacFileCache-53340D12.dat. I deleted this files. The problem still persists. Of course I also uninstalled the extensions and reinstalled again. I even reinstalled Dreamweaver. Unfortunately with no success.
Well, what to do now?
