All, Have ISPconfig 3 installed and have several websites running without problems. Added a new website the other day (birdman-teamholland.org) and installed wordpress on it. Everything ran fine, no problems whatsoever. Today I come home and find the server turned off, no error in the logs so no idea why, but turned it on again and everything works. Accessing the websites work fine, just the website birdman-teamholland.org gives me an "internal server error" all the time. If I access the page from a different PC not on my homenetwork then it works fine. If I turn off Apache all my other websites say, can't access, just the birdman website keeps giving "internal server error". Have no idea anymore and have tried a lot (.htaccess, new install etc.) What can this be?
