The plugin change url mai thumnail

hi @marty84,

Really Simple SSl doesn’t change image filenames, it only changes the image url from http to https.

If your site is slow it probably means you have slow third party resources, or a slow server. It’s not likely to be caused by Really Simple SSL. You can simply check this by using the “deactivate, but keep https” option in settings/ssl/settings

If the problem persists when the plugin is deactivated this way, there is some other cause.

I have deactive lazy load from my theme and back the thumbnail.

But, when I active your plugin I have this error

And very very slow…

Do you help me please?

You can manually add the .htaccess redirect by following these instructions:
