Ok it's some how gone for the forum after playing a while with the addons
but it looks like it isn't caused by any of them cause I reenabled all of them , but it still happens for XenCarta, but I don't know if it is a problem of XenCarta or any other addon.
The file is .../library/EWRcarta/ViewPublic/PageView.php on line 0. But I don't really know what this line 0 means.
I would be really happy if you could tell me what I should tell Jaxel cause it seems to be caused by the clear-code.
Edit: I have to add that I copied this code from the old Custom BB Code Manager where it worked quite nice with XenCarta.
