 * Hi,
 * when I’m precaching I’m getting strange errors for categorys. The log quotes 
   the following:
 * [https://www.torstens-buecherecke.de/category/thema/goblins/](https://www.torstens-buecherecke.de/category/thema/goblins/)
   
   This path is working and then: PHP Warning: file_get_contents([https://www.torstens-buecherecke.de/thema/goblins/](https://www.torstens-buecherecke.de/thema/goblins/)):
   failed to open stream: HTTP request failed! HTTP/1.1 404 Not Found Without category
   it is not working
 * I don’t know why category is lost in this case.
 * Regards
 * Torsten
