SG Optimizer Causing E-mail Errors
Using SG Optimizer, and hosted on Siteground Go Geek plan, we are having issues where Woocommerce order emails are not being sent. This only occurs if we don’t clear the SG Optimizer cache for a couple days. The problem is not specific to Woocommerce, but all emails from the website including our contact form, admin login notifactions from WordFence, etc. Not sure why the SG Optimizer cache plugin is interfering with emails, but we do use WP SMTP. Once the SG Optimizer cache is flushed, emails begin working just fine. I had reached out to SG hosting support numerous times, but they dismissed my concerns and blamed it on other plugins. But if I can clear the SG Optimizer cache, and/or disable the plugin, email then works fine. The problem obviously is within the SG Optimizer plugin.
Is there a way to automate/schedule this cache clearing on a daily basis? I just got done refunding 5 orders from the same customer because he didn’t get an email confirmation and kept submitting duplicate orders. This is getting costly. Thanks for your help.
