Same problem
It has been running fine for months now today it throws up the same error.
I removed the cache file, unnstalled and reinstalled but no joy.
What was the fix?
While executing timer in WA Universal Email.htm, the following Javascript error(s) occurred:
at line 449 of File
"....Commands\WA Universal Email.js":
Invalid array length
Im simply trying to add it to a blank php page with no other code.
