Hei everyone, don't know why, but my front-page exists, and also my projects are connected to this front-page, so they appear, after clicking. But when i try to reload the project page, it says this:

Anybody an Idea?

If you can live without the page transitions it should at least be temporarily fixable by disabling ajax/enabling compability mode in the laytheme settings, look for this:

its probably an issue with your permalinks

go to settings → reading → permalink

now make sure this is the structure:

or its an issue with your website url
maybe you moved your website to a new server but the old website url is still in your database? i think its probably not this issue, but you can replace all occurences of your old url with the new url by using the plugin "better search and replace"
