After updating website speed problem

Hi,

First of all I want to say we have been using your plugin since the beginning of our site and always worked perfect, thanks.
Since last 2 weeks we had speed charging problems so we updated all of our plugins one by one and check the speed after every updat. All of them but woocommerce that we did not update.
Right now the site works well without yours and slow with it. Of course, I think, without it active we cannot access the backend. What should we do?
Thanks a lot!
