[SOLVED] 403 error in add item Frontpage

when i disable your plugin everything works ok

Please read my posts carefully.

I asked you to enable only one K2 plugin and test saving an item.

Do this for each plugin installed on your site.

MEFG does not do anything in the saving process, so there maybe a problem in another plugin to work with MEFG.

PLEASE TEST EACH PLUGIN ALONE

ok
i disable all plugin and check it one by one
in all plugin is ok but when your plugin is enable show 403 error

Have you modified the plugin code?

No
even reinstall the plugin , but don't work

But I can see some differences: MEFG now displays group names not IDs as headers, and also checkboxes are displayed vertically not horizontally as on your site!

Also there is a drop down list at the bottom of the extra fields tab, when selecting "بله" from this drop down list, more fields are displayed below it, I don't think this is done by original MEFG.

You are right
I first thought because it is
But I re-installed the plugin and not the right
If you've re-install it again

I can't support the modified plugin, I don't know how it is modified!

The original MEFG does not affect the item saving process at all, and should not cause any problem in this step.

OK
i install original plugin
