Absolutely Horrible

By tugmariner on September 8, 2023

I'm a developer with multiple sites and caching on SiteGround is atrocious. It consistently caches pages it is configured to ignore and regardless of how many times you attempt to clear the cache sometimes it does but most times it doesn't. This plugin does nothing to alleviate those issues.

Aceleración notable

Have Had to Deactivate

When Optimizer is active it prevents product payments from being processed.

I have also used Lighthouse when it is active and found the site to run significantly slower.

Works well for my site

Siteground - Speedy and Helpful Service

By straitsailor on September 6, 2023

We've delt with Siteground since 2016. Still considered new-bies, but they have been fairly quick and helpful dealing with issues that have come up with us. We've used the online chat most often and they have been very helpful through that process. Their advice has been helpful and they will give it when asked. I can't speak to other providers, but we have been happy with their service and will continue to use them into the future. Thanks guys!
