Hello,
The automatic update did not work, I was asked to manually send the new files to the server.
Once done, I had a 500 error.
So I downloaded all the files from my client area and uploaded them. I no longer have the 500 error on my site, but I cannot continue the update I have this error :
I tried downloading/uploading the files a second time, clearing the cache, but I still have the same problem.
Regards
