I replaced my last backup (with 3.5). But when I try to open dashboard I get the following warnings:
Warning: error_log(/home/p34950/domains/column-razenberg.nl/public_html/wp-content/cache/e5ae3fe9f96cd093b698e408350d7b24.txt) [function.error-log]: failed to open stream: Permission denied in /home/p34950/domains/column-razenberg.nl/public_html/wp-content/plugins/wp-super-cache/wp-cache-phase1.php on line 462

After I see these warnings I change with ftp the names of cache and wp super cache. After that I can open dashboard but i can't activate new plugins.
So, the problem is not solved yet.
