I’m trying to installing version 2 Alpha of Invoice Plane, but during the DB installing process i got the following error
SQLSTATE[42S21]: Column already exists: 1060 Duplicate column name 'old_invoice_template' (SQL: ALTER TABLE clients CHANGE invoice_template old_invoice_template VARCHAR(255) NOT NULL)
So, i deleted manually the column “old_invoice_template” and the process continued, but then it asked me for other 2 or 3 fields more that were duplicated. this stay in a loop of errors of the same type. and the installation doesn’t finish succesfully
Php versión : 7.1
required modules: loaded
S.O: Windows 10
I wondering if some of you could help me to solve this.
