I am getting this error while installing india_compliance app on site.
Installing india_compliance…
Incompatible ERPNext Version:
ERPNext version 15.4.0 not compatible with India Compliance 15.7.0
Please upgrade {app_name} to version {required_version} or above to use the current version of India Compliance.
For now, If you want to install the latest india_compliance (v15.7.0) then frappe must be in the 15.3.0 and erpnext must be in the 15.15.0. so I think, you should update the erpnext.
