Hello @mcofficeadmin,
The issue you describe seems like a particular plugin conflict. We are unaware of any problems or conflicts between SG-Optimiser and the plugin you mentioned, nor with gzip.
As this might be related to the site configuration, we will need to examine it and probably create a staging copy to test and see what the issue is and how it could be resolved.
As such, access can’t be provided through the forum, please submit a support ticket through Siteground’s User Area so our team can check this further.
