I have gone through the plugins on my test site and found out the following:
When I inactivate alla plugins except ACF and it’s add-ons, the page loads just fine in about 7-9 seconds. I found out that the All-in-One Event Calendar is the plugin that slows the page down the most.
Also contributing to the slow load time is the plugins Collapsing categories, BWP Google XML Sitemaps and WP Facebook Open Graph protocol.
Another observation is that when all the plugins are activated as before my troubleshooting, the amount of time that it takes for the options page to load is around a minute. Instead of up to 4 minutes as it was before I started inactivating and troubleshooting.
Can the inactivation of the plugins itself have any effect on the load time?
