[solved] mod_userpoints2paypal

I disable SEF plugin system and no changes. PHP log errors is empty and have a blank page.

No, I was not mentioning the SEF system plugin but SEF in Joomla configuration page.
DIsable SEF and url rewriting if enabled.

It won't help showing PHP errors but at least trying to get clues by other way...

Getting Better.
Stric standards notices do not cause white pages.
Fatal errors do.

So the error to look at is
Fatal error: Using $this when not in object context in C:\xampp\htdocs\Joomla250\libraries\joomla\plugin\plugin.php on line 105

Is your site in english or in spanish when the error occurs ? It seems to be a language string issue.

FrontEnd is in catalan ca-ES languaje. Site Admin in Spanish.
I no have ativate multilanguaje.

Check your catalan translation for the module.

Try the module in english and see if error occurs in english too.
I guess it won't.
Let me know
