#298 – cant install version 3.11.1

 An error has occurred.
1062 Duplicate entry 'TEST10' for key 'Unique Coupon Code' SQL=-- -- Alter Coupon table -- ALTER TABLE `joom_taxibooking_coupons` ADD UNIQUE `Unique Coupon Code` ( `code` );

Hi frama,
since version 3.11 of Taxi Booking Coupon codes have to be unique and system will not allow duplicate Coupon codes.
From the Error you are getting it looks like you have coupon ode TEST10 twice in the Coupons section of Taxi Booking. Please verify that and remove the duplicate entry then try updating again.

Let us know if you still have problems after doing the above.
Hope this helps.
Best regards.

yes, installed successfully. thank you!

No problem at all.
Glad I could help.
