Saving CB User After Changing Subscription Times Out

SiteGround looked into it further and got back to me with the following, I can confirm everything work fine when I turn off the ACYMailing component.

========================================
I recreated the problem and I believe that it is somehow related to some of the Acymailing extensions. When I tried to save the changes, the PHP process handling my request started executing a large number of SQL queries like this:

UPDATE q74gf_acymailing_subscriber SET filterflags = REPLACE(filterflags, \"f619f\", \"\") WHERE filterflags LIKE \"%f619f%\"

The number of these queries was so large that until they execute, the script reached the apache timeout. I tried to increase it, but the issue persisted.

The changes started saving immediately and without any error after I disabled all Acymailing related extensions through the URL below:

www.emmett-technique-hq.com/administrator/index.php?option=com_installer&view=manage

You should report the problem to your developer for further investigation.
========================================

So can you please direct me would this be a CBSubs AcyMailing issue or an outright Acymailing support issue?

Seams like a problem in AcyMailing. We're not using their filter or tag API. We're using the below to give newsletter subscriptions to users.

Get the user to see if they exist in AcyMailing already:
www.acyba.com/acymailing/64-acymailing-developer-documentation.html#api_getusersub

Otherwise we create them:
www.acyba.com/acymailing/64-acymailing-developer-documentation.html#api_insertuser

Next add/remove subscriptions for that user:
www.acyba.com/acymailing/64-acymailing-developer-documentation.html#api_subscribe

We're not using any other AcyMailing API than that shown above. Our usage can be found in the below file.

/components/com_comprofiler/plugin/user/plug_cbpaidsubscriptions/plugin/cbsubsacymailing/cbsubs.acymailing.php

The usage we have is no different than their current documentation so I'm not sure what to suggest.
