Thank you for contacting u about your Data table plugin issue.
We do not restrict the number of rows inside Data Table plugin and the free version allows you to create as many rows as your server can work with.
So 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. Afterwards let us know about the result. This will help our developers to solve your problem faster.
And then contact us through our internal support. And we will help you to solve the issue.
