I have the same problem.
Yesterday I have moved a XOOPS web site (2.013.2) with xlanguage from an hosting to another and a welcome blank page appeared...
Permission and all was ok. Difference? yes. old hosting php 4.4.7
The new one, php 5.2.0 -8+erch15
So... Highlander, thank you very very much for your solution.
I've searched for hours, and this is the unique post the solve the problem!
Thank you again
Stefano
