MSM how to Syncronize a Site (w/ reSync Blueprint)

[AEMWizard]

We have a problem, one of our multi-lingual site, created with the blueprint. One of our MSM AEM sites is not connected at all. What can we do to ensure the site is working as expected?

/content/easde/language-master/en (language-master is the blueprint; en is the language copy);

/content/easde/CAN/en (connected to blueprint);

/content/easde/USA/en (connected to blueprint);

/content/easde/GB/en (not-connected to blueprint);

What can I do in the JCR to re-connect /content/easde/GB/en to the blueprint, so that I can rollout a page from /content/easde/language-master/en, and everyone should get the rolled out page?

Currently, rolling out from the /content/easde/language-master/en is actually rolling out to CAN, USA, GB as expected.

Hi AEM Wizard,

Can you please tell us whether /content/easde/GB/en is created as LiveCopy site ? or you are trying to establish the connection after the site is created? 

You can try below:

1. If the site is not created as Livecopy, you can try adding cq:LiveSyncConfig node under GB/en/jcr:content and cq:master property pointing to the blueprint site. You can refer other sites like /content/easde/USA/en where rollout is working and try to mimic same cq:LiveSyncConfig node and see how it works.

You can also check below and see for more info:

After this configuration, I am no longer able to roll out any of my pages.

What is the configuration you have added?

Which version of AEM are you using?

Please verify jcr:mixinTypes property present at jcr:content node or not. 

Also, you can verify below and see if that helps?

Check in the Blueprint Control Center.It shows successfully rolled out and failed ones in colod coding.You can also perform synch them to Global Blue Print core site as well.
