Sorry for my very candid question.
I tried to migrate my site at www.fnar.be
I tried with creating a specific folder \CMSIMPLE4 and everything worked fine
When trying to apply the update to the folder \cmsimple, I got an error 500
My provider did not find anything wrong but suggested to use the debug mode.
How can I use the debug mode withcmsimple ?
(I already migrated my other site www.bamf.be and everything worked fine without any problem)
Thank you for your help
For debug mode have a look on the FAQ: viewtopic.php?f=20&t=443
I never would use a folder "cmsimple", that's a system internal folder, another such folder could cause some confusion, even if it works,
