Hello Thomas,
The reason of this problem is "Coupons" plugin, we are going to re-made this plugin
taking into account our customers wishes, but now I have to post fix for current plugin version.
The first way to fix the problem is re-download and re-install the plugin, but in this case your coupons will be removed.
The second way is edit system hook which stored in the database, here the instruction:
1. go to your Admin Panel >> Database manager
2. copy the following sql query and post it to "SQL query" field.
Code:
Only registered members can view the code.
3. Click on "Go" button
4. System should run this query and update hook, you should get the following message as confirmation: Query was successfully ran, 1 rows effected.
5. Needs to run one more sql query to remove wrong entries made by plugin, copy the following sql query and make the same steps as you did with previous sql query:
Code:
Only registered members can view the code.
6. in result you have to get the same green notice, but effected rows can be more then 1.
Problem fixed, test add listing process again.
I am looking for feedbacks.
Thanks
John
