I didn't change anything, no new add-ons, no server changes. The only change was the XF update from 2.5.5 to 2.5.7, but I doubt any relation to the update. Otherwise I wouldn't be the only one with this problem
Is there any way to check the website's response when XF tries to convert the link ?
I just made a link title conversion test in the XF test area with my sites URL, but the link is also not converted
