Admin menu Plugins gives me white page

I have this strange issue when I click the Plugins link in admin menu on my xammp localhost, all I get is a white page.

All links incl. Plugins sub links works just fine and pages open normally.

So, here is what happened, yesterday while working on the site, out of the blue a big part of the links in the admin menu went on holiday! After searching for solutions I found out the DB tables got messed up:

wp _user_level was 0 changed it to 10 and
wp_capabilities got messed up too, added this code to the table:
a:1:{s:13:”administrator”;s:1:”1″;}

After fixing this two tables I got back the admin menu and all it’s links.

I’ve replaced all core files but still cannot access Plugins page, everything else works just fine.

Wonder if I overlooked some DB table that might have anything to do with it?
