Good afternoon, install your template and everything is fine, only I have a problem installing a plugin (Modern Events Calendar Lite), the jQuery comes into conflict and causes the page to send a message “The site is experiencing technical difficulties”. I have already been dismantling and activating the other plugins and say what is causing this conflict “Cesis Custom Posts” what can I do to make it work correctly?

Error Console

Good night, install the "Modern Events Calendar Lite" plugin and this bug started to appear, if I unsettle the site it looks normal.

Este es el plugin: https://es.wordpress.org/plugins/modern-events-calendar-lite/

Good afternoon, I don't have any additional add-on installed just the one mentioned.

I already tried to deactivate all the add-ons and then go on enabling one by one and everything works fine. I only have the problem when I activate the "Cesis Custom Posts" plugin.

It is being developed is a corporate website.

Have a nice day!

Best regards.
