Internal 500 error after installing PaymentMadeSimple

[Kaylen]

I am using CMS 1.11.10, CGextensions 1.30, FEUsers 1.23.5 and I tried installing PaymentMadeSimple from the ModuleManager webinterface.
When installing, it said I also needed to install CartMadeSimple and ShopMadeSimple, I clicked on 'install' and then my entire site went down. No frontend (internal server 500 error) no backend (just a blank page), I could not delete the installed modules via FTP and also not via Pleask. Eventually I renamed the module folders via FTP to f.i. PaymentMadeSimple_old (did that for al 3 folders) and now my site is working again.....very very strange.....

These are the errors in my log file:
[Sun Jul 13 14:51:58 2014] [error] [client 62.194.74.122] PHP Notice: Undefined variable: taboptarray in /var/www/vhosts/2beinbalance.com/httpdocs/modules/CartMadeSimple/method.install.php on line 171, referer: http://www.2beinbalance.com/admin/modul ... ize=145857

Can someone please help me fix this?
Thank you very much!

I don't believe it's up to date and working in current version of CMSMS.

Ah ok, you cannot see that Message from the webinstall page within the cms.

What i actually want is to have a download on my website, which Will become available after you pay. Can you or anyone tell me if that is possible within the CMS and what plug-in I should use?

Thank you!

Normally ModuleManager installs every time the last module version. But maybe this is not really useful in your situation cause CGExtension is under development but Cart/Shop/Payment Made Simple it isn't.

The only chance I see is trying to install the CGExtension version which was the current one as last version of Shop Made Simple was released.

The description of these modules says they are ready for 1.11.

The last change log of shop made simple says "Version can only be used as of CMSMS 1.10;"...

Really curiously - function MaximumCMSVersion() says 1.11.9
