Scalability Pro plug-in

prevented the loading of websites.

after shutdown everything works, what could be the problem ??

Pages load properly after disabling this plugin. I would like to add that this only applies to pages, products with the plug-in turned on worked properly

And this plugin: Super Speedy Search

it is still out of date and cannot be updated to a newer version

A new version of "Super Speedy Search" is available. See version 2.09 notes or run an update.
