Hi,
Thank you for your reaction.
I’m running a self-hosted environment. With PHP version 5.6.30 and MySQL version 5.6.35. I’m using the Brooklyn WordPress theme by United Themes
The other plugins that i have are:
– Contact Form 7, Version 4.7, by Takayuki Miyoshi
– Easy Theme and Plugin Upgrades, Version 2.0.0, by Chris Jean
– Portfolio Management by United Themes, Version 3.9
– Pricing Tables by United Themes, Version 3.0
– Shortcodes by United Themes, Version 4.2.4
– Slider Revolution, Version 5.3.1.5, by ThemePunch
– Twitter by United Themes, Version 3.1.1
– WPBakery Visual Composer, Version 4.12.1, by Michael M – WPBakery.com
– Yoast SEO, Version 4.7.1, by Team Yoast
I tried deactivating all the plugins except Event CLNDR, but I still got the same error message. Could I be missing some kind of script?
Thank you!
