Today I found a weird error with our Magento installation. Before the weekend but today I am getting weird random redirects to homepage/index.php. I first noticed it when using the Backend, when clicking something I was redirected to homepage/index.php.
After this I began investigating. I noticed that it also happend in the frontend. Completly random in my eyes I was redirected to homepage/index.php. There aren't real specific pages on wich it happens but just random.
I could click the Magento logo in the topleft in the backend for ten times and the next click it would redirect to homepage/index.php. The second time it only took a couple of clicks, so like I said completly random.
You can recreate the error by visiting www.easytubs.nl and clicking the logo a bunch of times. Mostly it works fine a few times but sometimes it will redirect you to /index.php. This also happens to categorie links, product links and backend buttons/links.
Do you guys have a suggestion?
Make sure if you are running version 1.9.0.x that you havr the security patch SUPEE-3762 applied. This looks like someone is exploiting the denial of service attack that this patch fixes:
Did you have any luck with a fix for this error? We are having exactly the same problem,
