Maxmenu Module does not appear on some pages

I am having a problem with the Maxmenu module. Sometimes the menu module does not appear on a page.
See screen shots.
This has just started happening with Chrome browser.
There is no problem when I use mobile menu. I am also using Template CK as my template
Any ideas what might be the problem?
I am baffled ????

Hi
are you using a compile css, cache or optimisation tool on your website ?

Yes
JCH Optimize www.jch-optimize.net/

then you shall check with it
you can try to disable it and see if the error appear again to know if it is in cause or not

Sometimes the menu module does not appear on a page

sometimes = problem
if you can tell me when it occurs, I can have a look, else it is quite impossible to debug online

Hi Cedrick,
I disabled the JCH Optimize plugin.
The problem looks like it is fixed. There are some options in JCH Optimize to exclude css optimisation. So I have done that for MaxMenu (see screen shot) i will monitor it over a few days to see what happens

Ok, the problem occurs again even though set JCH optimize to ignore the module in my previous post.
I have disabled JCH Optimize again.
I am looking at their troubleshooting documentation
JCH Optimize troubleshooting
If any MaxmenuCK user has JCH Optimize installed I would be interested to hear their thoughts.

Kind regards
David
