What version of RH? Is it happening in any of the sample projects?
RH 2015 (220.127.116.110)
We have spent the last few days basically republishing all our projects (version rev with all the software). This project was the only one we've found with this problem. I haven't tried the sample projects, but it's clear it's not happening to all of them.
I reckon your language file is corrupted.
You could try replacing the RoboHHRE.lng with a working one as per the last post in this topic:
You may need to delete the cpd file as well.
As always, make sure you have a backup, in case.
OMG that did it. I hadn't seen that other thread. Thanks so much!
