Cannot save configuration, back to homepage

-- HikaShop version -- : 2.6.3
-- Joomla version -- : 3.5.1
-- PHP version -- : 5.5.34
-- Browser(s) name and version -- : Firefox 46.0

Hi,

I've tryed to solve this isse without success. I've tested on a subdomain with a fresh joomla installation and latest hikashop (starter) version.

When I try to save the configuration it redirects me to the homepage.

What's the problem?

Hi,

I seen that issue once ; when the server have some "content" limitation on the "post" size or on the number of "post fields".
In such condition, the form is not fully submitted and some elements (which are at the end of the form) are not send ; it results that the configuration is not saved and if there is no joomla parameters (option, ctrl, task), the homepage will be displayed instead.

Regards,

Thanks Jerome for reply.

What to do?

Hi,

If you have access to the server configuration, you'll need to check the settings of the security modules you installed for your PHP like mod_security or SuHoSin.
If not, you need to talk to your hosting company.
The exact name of the setting to be changed will depend on the security system used and how it's configured, so we can answer precisely. As Jerome said, it must be linked to the "post" limitations.
