I've installed jticketing and everything went perfect but then I restored an akeeba bakcup of my site where I didn't have jticketing installed and I receive this error when I try to install it again:
JInstaller: :Install: Error SQL Unknown column 'payment_gateway' in '#__vendor_client_xref'
Extension Update: SQL error processing query: DB function failed with error number 1054
Unknown column 'payment_gateway' in '#__vendor_client_xref'
ALTER TABLE `#__vendor_client_xref` ALTER COLUMN `payment_gateway` SET DEFAULT 'NULL';
Package Install: There was an error installing an extension: com_tjvendors.zip
I've tried it in two development sites and I receive the same in error in both sites. When I look at the dbase structure, vendor_client_xref doesn't have any columns so the error is coherent with the db structure but I do not know why that table is empty.
Any hint to solve the problem?
