I have critical problem!
My Wordpress Blog has the permalink structure
The problem is that very often the permalinks break so I get a lot of 404-Errors.
I can fix it refreshing the links by saving the permalinks options again in the admin panel.
This seems to be a knows problem. I find out that some wordpress users got the same problem, but only one! After a refresh all works. For me it breaks after some hours again. Sometimes I noticed that while working on my blog and most times I noticed it by checking the links in the morning.
That's why a lot of users leave the site after seconds, so sadly I loose a lot of traffic...
I activated the plugin
WP No Category Base, this could be the problem. But on another blog this plugin worked for months without trouble.
I can tell you everything about my server configuration (cheep virtual server from xenonserver.de) you need to help me. There is enough memory available.
Installing a plugin, the install dialog freezes, so I waited some secs and then went back to the plugin overview. But every plugin is listed there and works fine.
