# The Tag Groups Administration Page Doesn’t Load

Some users have reported problems loading the list on the [Tag Groups](https://publishpress.com/links/tag-groups) admin page. In most cases, this is caused by another plugin. The other plugin causes your site to output a warning or alert that interferes with the data transfer to your browser.

## Try disabling other plugins one-by-one

Try disabling other plugins one-by-one.

If you can see the JSON data, that may give you a hint about the plugin causing trouble. Check any text before the opening curly brace. For example: `Warning: xyz in /some-plugin/index.php{"data":"success" ...`

## Try other steps

Go to the "[Tag Groups](https://publishpress.com/links/tag-groups)", then "Tools", then "System Information". Check if the "Ajax Test" option shows a green check mark. If you see a red X, [this post has more information where to search](https://taxopress.com/docs/debugging-a-wordpress-ajax-error/).

Alternatively, you can [open the JavaScript Console in your browser](https://webmasters.stackexchange.com/a/77337) on the Tag Groups Administration page. Reload the page and check the error or log messages for anything that gives a hint about the cause.

A final suggestion is to add the following lines to your wp-config.php file. Then reload the Tag Groups Administration page and check the content of the debug.log file in the /wp-content/ folder so see if there is any error message.
`define( 'WP_DEBUG', true ); define( 'WP_DEBUG_LOG', true );`
