Thank you for the response Steven…. I do mean Lightspeed Cache.
Our host jumped to switching us to php5.6 instead of giving that option, so we are going through the steps of turning back on PHP 7.0 and disabling Lightspeed cahce.
We have yet to hear anything from LightSpeed Cache. Our Theme Support has confirmed that they are PHP 7.0 compatible as we expected.
We will disable the cache and try it.
WOuld a cache cause those cookie errors?
Sorry I have some knowledge and am always learning from all of you.
