Same problem on my site tOO! :(

How can i fix it?

What I gather here we are dealing with three scenarios, one is a fixable problem that of a well established 1.3.1 that was up and running and any migration was done prior to 1.3.0. 

A not so easy to fix problem where as whilst the product was 1.3.1 and a data migration from wall.fm took place and notably the version number changed to 1.3.0 after a successful migration.

Then we have an last problem of 1.3.2 successfully installed with the cron working etc but the migration from wall.fm can not be successfully implemented. 

Josephs methodology will successfully work for those that migrated there wall.fm data using 1.3.0 or a prior version. Joseph can not of course simulate the problems of the last two scenarios.

Could you please quote what scenario your having a problem with so as to stop any form of confusion. This will then help Oxwall to suggest a solution in reference to the correct scenario I hope, or someone that has found a solution.   

   

I had to go back and reinstall  1.3.1 and import my db all my users is there but their login don't work had to mail them all to reset their passwords according to my host Oxwall have a problem with the .htaccess file.

What exact problem did you have with your hosting? Can you ask them about this? Such information could be helpful for other users.

They told me that Oxwall upgrade write something to the .htaccess file that messed it up. It happen again to me just now, I upgraded the Friends plugin and now I have a blank white screen and I just had my site running smooth on 1.3.1 all my users back and now this! there is no page source at all.
