problem with Plugin Accordeonmenu CK Params - J2.5

yes I have got it
but ... I don't see where is the problem. Do you have another website on this server where you can test ?
This could be due to a security rule, but I can not be sure .Anyway this should work without issue !

hmmm, I don't have any working website at J2.5 on this server. I know that there can be a problem with J2.5 with this hosting but everything else is working fine...
Can it have something to do with any other plugin/module?
Maybe tomorow I will have a few minutes to install clear J2.5 on this server - I'll let you know.

ok let me know
for info I have checked your other installed extensions and I have not found anything that can cause this

We could do something else - if you are interested I (or you personally) can check whether there will be the same problem with maximenu params plugin

I moved this site to different server with akeeba backup and... there is the same problem...

hmmm... another try with clear installation of J2.5 and the same problem...
i'll sent you admin access per email to both sites in few moments
