Custom loyaltys prestashop module not saving the values

[campeom]

Hello

 

I have an strange problem with the Custom loyaltys (the prestahop module, not yours).

 

I cant change the value of point - euro and the name of the voucher details. I chaneg it but when i click sabe... nothing happens... and the values dont change.

 

Do you one who can help me, even paying money.

 

Is strange, because un localhost, in my Windows pc, it Works perfect, but when i place the files in the Linux server.... i doesnt work.

 

 

It look like it cant sabe the values because or permissions, but i cant finde the root of the problem.

 

Thanks

 

Oscar.
