Not sure whether this issue has been identified by others, but I have just recently encountered a problem with the Excel-like backend editor after updating from version 1.7.1 to 1.7.2.  It doesn't save new records when using Chrome v57.0.2987.98, and the Excel-like backend editor does not appear at all in Firefox v52.0 (32-bit).  Anyone else facing the same issue?

Curious on the version being used at the sandbox.  A quick test seems to be work properly over there though.

Anyway, currently reverting back to the working 1.7.1 because I rely on Excel-like to duplicate & edit records in the backend.

Hi Bogdan,

Thanks for the prompt response.  Didn't see any change when deactivate/active the latest plugin.  Spending a little more time checking on this, I found that after clearing the browser cache, reload the backend Excel-like editor and using Chrome Developer Tools, the console shows "Uncaught SyntaxError: Unexpected end of input" for /wp-content/plugins/wpdatatables/assets/js/wpdatatables/wpdatatables_excel.min.js?ver=4.7.3.  Digging into the 1 byte wpdatatables_excel.min.js file, the content is just a "-".  Redownload from CodeCanyon for the latest v1.7.2 plugin shows that same file has the same single "-" content. Anyway, replacing wpdatatables_excel.min.js with the older copy from v1.7.1 (around 22.9kb in file size) seems to allow the Excel-like backend editor to appear and save/edit/delete records.  Not sure whether the older copy will break anything, but I guess I will find out soon enough.

Thanks for the replies.  Currently I think I've solved the issue a few days ago.  I'm guessing the latest plugin zip installer came with an incomplete minified wpdatatables/assets/js/wpdatatables/wpdatatables_excel.min.js.  All I did was using JStool in Notepad++ to minify and save a .min.js version of wpdatatables/assets/js/wpdatatables/wpdatatables_excel.js from the same directory and it has been working since.  Will keep in touch again if anything weird comes about.
