Hi,
several users are reporting crashes when using EMC, which seem to appear since 19th of April.
Also the following thread is related: http://openpli.org/forums/topic/33497-nach-update-gs-bei-emc-und-umschalten-auf-liveprogramm/
The crashlog just states:
FATAL: unbindAction with illegal python reference
(see the linked thread for crashlogs).
According to the statement of one user, the crashes also appear when replacing the current EMC version against an older version, so probably a change somewhere within Open PLi, which seems to happen shortly before 19th of April seems to cause this issue.
Kind regards
Hounce
