XF 1.5 Thread tooltips not showing


Active member

For some reason my tooltips are not showing anymore. For the life of me I can't figure out why this:
First thing I did was switching style and tooltips show with other styles so it must be my style.
Yet I just can't find what did this.
I changed the style.css recently but even when I revert back to it's previous version, it's still not showing tooltips.

Any advice? Could it still be an addon issue?
