Javascript errors

We are seeing the following event espresso javascript errors on all our wordpress pages. Is this something that you are aware of on other installs or have an understanding of why they would be appearing?

They don’t seem to interfere with the event functions, but we are concerned they are slowing down our site.

Hi there,

Which JS errors? Can you post them or a screenshot here?

Or a link to an event I can view?

Which version number of Event Espresso are you using?

Thank you, we fixed those in version 4.10.30 (HERE)

Please update to the latest version of EE (4.10.37.p as of this reply) and see if you have the same error then.
