Ok, here is what happened.
I am using a totally stock version of Integramod140 with all the latest updates etc.
I uploaded the acidtech folder contents to the templates dir.
I went to extreme styles in admin and installed all the acidtech colours.
I did not set it to default and people can chose their own style
I went to my profile to select acid tech as my default theme.
Nothing happened. No change. And what is worse the annoucments stop showing in the portal. I checked the annoucments id and it is ok.
I downloaded the zip again and reinstalled it, still no change.
Also, when i try now to slectec suborange or sub blue (used to work) no longer work, so i am stuck with f1subice.
I saw it has happen to some one else before but they got no solution.
Any ideas?
Thanks.
