TypeError: 'undefined' is not a function (evaluating 'c(d.target).zIndex()')1 user found helpful
Hope someone can help here.
Never seen this happen before but we upgraded a site, which we have done many times, and one of them does not work properly.
The site looks fine but as soon as you try and edit a block ANY dialogue box does not pop up to allow you to edit.
Looking at the inspector we get the following error within jquery:
TypeError: 'undefined' is not a function (evaluating 'c(d.target).zIndex()')
Anyone seen this before? Anyone why this is happening.
You need to check the developer console and see what sequence js assets are loading in.
It could be a theme thing, perhaps an old theme that loads all assets into the header rather than the footer.
Something must have happened with the update so moved the concrete folder from teh updated version to the top level. Fixed it.
