Cannot Add or Delete Catorgories

Hi I am having a small problem with my site https://www.soapncandles.co.uk I am finding that since I installed the security patch I cannot Add or Delete Catorgories from my site.

Is anyone else having this problem or have I done something wrong.

There is no problem with my other site https://www.handmadesoapncandles.co.uk which makes me think that it is not the security patch thats causing the problem.

If you have any ideas I will be grateful
Regards Andrew

I've heard this reported elsewhere. Often with that same comment that other sites seem to be working fine.

What version of Zen Cart are you using? What add-on mods do you have installed?

Hi Kuroi,
Thanks for the reply I am using 1.38 and as far as I know I only have Easy Populate and new templates.

I have exactly the same added as I have with my other site and that site is working as it should.

What about your category structure? Have you mixed products and subcategories in the same category?

No there are no mixed catorgories that was the first thing I checked, Just cannot work it out.

When I do press the delete catorgories it just goes straight back to Admin Home

I have just worked out what was wrong and have sorted it.

It was somthing to do with this section

To amend the <YOUR ADMIN DIRECTORY>/includes/functions/html_output.php by hand is fairly straightforward.

However before attempting to edit this file, please make sure you have a secure backup of the original version.
Open the file in an editor and find the function "zen_draw_form"

The last line of this function is

return $form;
Just before that line add another line as below

$form .= '<input type="hidden" name="securityToken" value="' . $_SESSION['securityToken'] . '" />';
You can then save the file.

I changed it as it says here and that is what caused the problem as I have just overwritten the whole PHP in functions and it is now working as it should.
I do hope this helps others and thanks for your help Kuroi
