I support two multi-portal DNN installs (think 25-50 Portals). Both sites are running DNN 7.4.2, both have been upgraded from some previous version of 7.x.
As of late both installs have developed a nice little glitch where all of the sudden the tab order is rearranged in multiple portals.
Both of the sites were compromised with the Host hack that changed the host setting, but have been fixed for a long time and settings restored.
I haven't been able to nail down what causes the issue or how to fix it other than reset all the tab orders in each site.
The site does have a custom control panel based off of the control bar from DNN 6. So maybe that is throwing in a gremlin?
I updated the drag and drop stored procedure as mentioned in this thread: http://www.dnnsoftware.com/forums/threadid/477273/scope/posts/threadpage/2/page-order-gone-wacky-multiple-portals
I have run and fixed all the issues as outlined in these two scripts:
Anyone have any ideas? Since there are so many users on the site all the time in different portals I haven't been able to nail down the cause of the issue or a quick fix.
