# JS console errors – MainWP v4

 * Hello,
 * I’ve upgraded to MainWP Dashboard v4, following the handy upgrade guide/faq. 
   After upgrading, and after transitioning to v4 extensions, I’m seeing a couple
   of JS console errors come up on numerous pages within the MainWP dashboard.
 * The console errors are being generated by one of the scripts in the extension
   MainWP Client Reports: `/wp-content/plugins/mainwp-client-reports-extension/js/
   mainwp-reporting.js?ver=1.4`
 * The console errors are:
 *     ```
       Uncaught TypeError: jQuery(...).tooltip is not a function
           at mainwp-reporting.js?ver=1.4:854
       ```
   
 *     ```
       Uncaught TypeError: jQuery(...).datepicker is not a function
           at HTMLDocument.<anonymous> (mainwp-reporting.js?ver=1.4:3)

 * This isn’t exactly causing me any trouble, but just thought you should be aware.

 * Actually, it does seem to be causing some trouble. With the extension activated,
   and with those console errors present, there are certain things I cannot do within
   the dashboard, such as viewing the table of all of my sites (they simply won’t
   load).

 * These errors occur after updating if you are using cached versions of the javascript
   files from the previous version. It should clear up if you clear your browser
   and/or server cache, as noted in [this post](https://wordpress.org/support/topic/sync-child-site-button-doesnt-do-anything-v4/).

 * Interesting. I had done a hard refresh (clears cache) a couple of times after
   the whole upgrade process and was still seeing those errors. One more hard refresh
   and they’ve all but cleared up now.
 * I didn’t think that post you linked was relevant to me. But it does touch on 
   a broader issue. If JavaScript breaks in the MWP Dashboard, the dashboard becomes
   border-line useless, since so many aspects of the dashboard rely on JavaScript
   to function.
 * Marking this as resolved.
