Thank you for contacting us about your Data Tables Plugin question.
The first thing why this had happened – the plugin was installed incorrectly – please try to turn off pro and free versions one by one and delete. Then install and activate in the order – free and then pro version. Clean cache in your cache plugin and browser cache.
In the case this will not help –
most likely there is a conflict with your other plugin or your theme. We hope you understand that we can’t test our products with all other plugins and themes that are available on the market, and we can’t control the other developers. Therefore bad code of other plugins or templates can provoke a lot of problems.
Please try to deactivate all your plugins one by one and check the issue. Thus you will find out which plugin causes the error. If it won’t help, try to switch temporarily to a standard WordPress theme and let us know.
I you don’t find the plugin or theme that causes the disappearing – please contact us though our internal support – we will help you to solve the issue.
