Error Message with Uncode template

We are getting an error message from WordPress with the below content.

Error Details

An error of type E_ERROR was caused in line 33 of the file /home2/ernc1mmu/public_html/wp-content/plugins/uncode-core/includes/vc_extend/init.php. Error message: Possible integer overflow in memory allocation (4294967263 * 32 + 32)

We hired an external developer to create our website but they are no longer available. Any recommendations?

Hi,

Please make sure you are using latest version of WordPress, theme and plugins.

Thanks

Thank you very much. We are using the latest plug-ins. Seems the plug-in itself needs an update. Appreciate your help.
