Hello

I have been waiting a long time for this hikaserial subscription after successfully using akeeba subscription, emerald.
First quarter of an hour of discovery:
1) Installation OK
2) Dark blue menu bar with invisible controls

3) Unable to create a new plan.

Message:
"1054 Unknown column 'pack_email_inherit' in 'field list'"


Tank You
Some research but I could not create a new plan !!!

Hello,

Ok for point 3

Another point now appeared:

4) In the view of the "Plan emails" tab

here is the error: 1146 Table 'ghxt_prosystemefr2. # __ hikaserial_ack_email' does not exist


Tank you

Bonjour Jérome

0K pour le point 4)

Point 2) Dark blue menu bar with invisible controls
Je ne comprend pas ta réponse :

PS : Your backend menu color is not related to HikaSerial. There is indeed some CSS to handle menus in HikaSerial but that's for the legacy menus, since a long time HikaSerial is using the HikaShop menu and so its CSS.

5) Erreur sur enregistrer suite à modification du plan :
Je modifie le plan et je click sur enregistrer :


Voici l'erreur:


Heureux de vous aider et bonne journée
Nota: Je suis très intéressé par cette extension que j'attend depuis longtemps pour simplifier les abonnements suite à l'acquisition des produits à télécharger sur hikashop.

Ok resolved => 5) Error on recording due to plan modification:
I just tested all the basic commands:
New plan, Edit and Delete and everything looks OK


Remainder Error Item 2) Dark blue menu bar with invisible controls
I do not know what to do ???

Have a good day
