I am having in issue whereby on certain pages, the mobile “hamburger” menu appears in the header (upper left) even though I am using a standard desktop browser (I checked chrome, FF and edge they all have the issue). The only pages it happens are those where I display data from the wpDataTables plugin, however I have tried many other themes but can only see the issue when using Sparkling.
Here is a page with the issue: Data Tables
All other pages behave like the front page.
Yes you are right - as mentioned the hamburger menu only appears on the data page.
Just to make sure that I didn’t mess this up with customizations, I went ahead and setup a brand new wordpress site, installed the theme Sparkling, then installed the wpDataTables plugin and created a data page. Without any customizations whatsoever this issue occurs (data pages only as mentioned).
So the short answer is that there are no customizations - it is all out of the box stuff.
this problem is caused by the wpdatatables codecanion plugin if you deactivate it the problem will disappear, but if the plugin is must have you can use this css:
