Hi. I was just trying to change my author base and i found this plugin, then installed it ad everything seemed fine. then i changed the author base with this plugin but that just resulted in that i couldnt find my author permalink eighter on the previous /author/ nor at the new url i specuified. Well i thought id go again and i resetted everything from the top button in this plugin config page and went again. After i did that i cannot access any other page then my index and some other stuff works like /?s=whatever and /?p=22. it seems like this plugin has deactivated my previous (pretty) permalinks with the defaults but i dont know if i actually are able to find anything since i have no idea what my post IDs are.
When i try to click on the links on my index which still links like they used to /my-post-url I get the dreaded 500 internal server error. I cant even get into the wordpress control panel anymore.
Hope someone can help me out here!
