this is a followup to: WPML String Translation and Cornerstone
I finally managed to set up a staging site and fix the “number of files” issue.
How ever, even I essentially mirrored the site, I can’t reproduce the issue on the staging site.
RECAP: If I activate wpml string translations on the live site, I can’t edit pages in cornerstone due the “iframe error blah blah…”. Decativating this plugin - all’s roger. As said: this works on the staging site just fine, so I’m kinda “wt#”, duh…
