Solved. by using FileZilla and SFTP to manually remove the 7.9.0 iteration and upload the 7.8.2 of WooCommerce. Issue solved as such.
Same issue here. However, It seems I am unable to even rollback to WooCommerce 7.8.2 – I installed the RollBack plugin, and initiated the rollback – however at the bottom of the log it notes ‘update failed’ and I see that the WooCommerce version has remained 7.9.0 – Do you have any suggestions for me on how you were able to RollBack ?
