Add module error

[Vowelwb]

I am having problem with module installation.

Whenever i try to install a new module by clicking on the 'Add a new module' button...nothing happens..page reloads
but no upload box asking for file upload comes.

I thought the problem could be with my version of the prestashop i.e 1.6.0.14 so i donwload '1-Click Upgrade' and try to upload it manually on the module folder..( as 'Add a new module' is not working )

Module list is not updating with new module name.
I have cleared filter and read forums and docs for it but still haven't found any solutions.

I have attached screenshot of module page of backoffice( prestashop dashboard) which help you understand my problem.

I am myself a developer..but i couldn't get through this..can you guys please provide a proper solution for it.

=== TIP 1

using native PrestaShop File Cache can cause 'unpredictable' results

 

back office-->advanced parms-->performance-->scroll  to bottom.

if enabled, disable and re-try.

 

=== TIP 2

Many hosts have implemented hosting cache which you do not see.  Most often they will use 'Varnish'.  PrestaShop does not behave well because it is more dyanmic than 99% of wordpress sites.  Contact your hosting to see if your hosting package has varnish and see if they can disable or give you access to clear.

 

=== TIP 3

 

As for your description of override, you can disable overrides in back office-->advanced parms-->performance-->

and then recreate problem to see if any affect....
