I updated to latest and bug still there.
Why would the language file have anything to do with setting a parameter to send to the server to retrieve JSON for a search filter?
Basically there is no “op” parameter
(Using latest FireFox & Chrome for testing)
Parameters sent by jqgrid to server are:
_search:true
nd:1398276446911
rows:20
page:1
sidx:TITLE
sord:asc
TITLE:test
