Upgraded this EE1 site to EE2 (not without issues but managed to get most of them fixed followed this Upgrading an EE1 site to EE2 with nGen File field as a guide but forgot 1 field). I'm stuck with 1 issue regarding 1 ngen file field that I forgot to convert to a text field.
This ngen file field sits inside a matrix field in just 1 entry in 1 channel.
I'm simply trying to delete this channel and its channel field group and recreate it without the ngen file field but I keep getting an error when I try to access the field:
An Error Was Encountered
Unable to load requested field type file: ft.ngen_file_field.php.
Confirm the fieldtype file is located in the expressionengine/third_party/ directory
When I try to delete the field the error is:
A Database Error Occurred Error Number: 1091
Can't DROP 'col_id_15'; check that column/key exists
ALTER TABLE exp_matrix_data DROP col_id_15
Filename: third_party/matrix/ft.matrix.php
Line Number: 1544
Any suggestions on how to tackle this?
