All 1.8 plugins showing incompatible (1 Viewer)

[bleugt]

Hi, I recently installed MediaPortal and was trying to configure the xmltv plugin, however none of my plugins will let me tick the boxes to enable. I have a message at the top of the plugins screen saying plugins are incompatible. I searched and could not find any info on this. Is this a known issue with version 1.8? Any ideas?

Thanks!
