Then place your schema-file with the name {package_name}.mysql.schema.xml in the folder core/components/{package_name}/model/schema/.
Continue with the button ‘parse schema’ and check if that works (should create a new folder core/components/{package_name}/model/{package_name} and some files in it).
Always make sure that the field ‘Package Name:’ in the form above is filled out!
I think MIGX wants to create a directory with the permission 777, but you don’t have the rights to do that.
mkdir($packagepath, 0777);
Have you tried to create the directories yourself (as described in my post above).
Or you could change the permissions in the file core/components/migx/processors/mgr/packagemanager/packagemanager.class.php to mkdir($packagepath, 0755); and see if that works.
I started from new again with a new database and modx install. I installed the MIGX extra and changed the packagemanager file as per Bruno17’x github file.
MIGX still didn’t work but by working through the system error log it appears that the assets and assets/components folders had permissions set to 775 i.e. writeable by group. After changing to 755 it appears to work.
I shall continue to explore MIGX as per the MIGX video and see how I get on. Hopefully no more issues.
Thanks once again for all your help.
