Hi!

running CMSMS 1.11.7 with PHP 5.3.25
On my test site I cannot update Cart 1.8.4 to 1.9. After the update is finished
with no error messages, the browser screen becomes a white page. The in log page
for administrators is a blanc page as well.
When going back to a previous page in the proser history, only a text only
version of the modules is display and still working.
The public access to the website remains intact.
Similar upgrade on a production site went without any problem.
tried several options; removing 1.8.4 instead of upgrade: same effect.
With CMSMS 1.11.6 the effect was the same.
Emptied the cache (via FTP as admin panel cannot be accessed) : no effect.
Changed admin theme before update from ncleangrey to one eleven: no effect.
made postings in the forum with this issue (both dutch and international): no
response
removed all registered products from the databases: no effect.

I do not want to wipe out my test system, only remove/update the Cart module

Greetings

Marc
