It is alway better to update all the files from the new release including css and language files.

I am not sure where the original came from but it had the following...

    search : {
        caption: "Search...",
        Find: "Find",
        Reset: "Reset",
        odata : ['equal', 'not equal', 'less', 'less or equal','greater','greater or equal', 'begins with','does not begin with','is in','is not in','ends with','does not end with','contains','does not contain'],
        groupOps: [    { op: "AND", text: "all" },    { op: "OR",  text: "any" }    ],
        matchText: " match"
    },

The latest file in jquery.jqGrid-4.5.2 has a  odata:{oper:'eq',text:'equal'}  vs odata[{'equal' ...

      search : {
        caption: "Search...",
        Find: "Find",
        Reset: "Reset",
        odata: [{ oper:'eq', text:'equal'},{ oper:'ne', text:'not equal'},{ oper:'lt', text:'less'},{ oper:'le', text:'less or equal'},{ oper:'gt', text:'greater'},{ oper:'ge', text:'greater or equal'},{ oper:'bw', text:'begins with'},{ oper:'bn', text:'does not begin with'},{ oper:'in', text:'is in'},{ oper:'ni', text:'is not in'},{ oper:'ew', text:'ends with'},{ oper:'en', text:'does not end with'},{ oper:'cn', text:'contains'},{ oper:'nc', text:'does not contain'}],
        groupOps: [    { op: "AND", text: "all" },    { op: "OR",  text: "any" }    ]
    },

I hope this post helps someone avoid this same problem.
