Cant log in after use of localitazion

Hi
I use wordpress.com for the blog: https://salebybygdegard.se.linweb42.kontrollpanelen.se/

I have FTP rights.

Yesterday I installed wp Easy booking and drove Rescan in Localization and the blog crashed .
When I try to login I get this error message:

Warning: fread () [function.fread]: Length parameter must be Greater Than 0 in / home/web75802/domains/salebybygdegard.se/public_html/wp-includes/pomo/streams.php on line 113
