# Error loading block: Invalid parameter(s): attributes

 * [7 months ago](https://wordpress.org/support/topic/error-loading-block-invalid-parameters-attributes-12/)
 * I’ve used Tag Groups to create an Alphabetical Tag Index on a webpage I’ve named
   Topics. I used the block editor to build Topics, which only has this one block.
   Nothing else.
 * While Topics continues to work fine, in the months since I created and configured
   it something has gone wrong. When I open Topics in WP to change the configuration
   of the block, I get an error message that reads, “Error loading block: Invalid
   parameter(s): attributes”. I’m not a web designer. I have no idea what this means.
 * Since originally configuring Topics, I’ve used TaxoPress to create two new private
   taxonomies. And I installed the plugin Admin Columns, hoping that I could use
   it to sort my posts using one of the new Taxopress taxonomies. I did not succeed
   in the latter, so Admin Columns is now deactivated. These are the only two taxonomy-
   related changes made to my site since I last knew my index page to be working.
 * Troubleshooting steps I’ve taken:
 * I’ve tried creating a new page from scratch and inserting the Alphabetical Tag
   Index block in it. This doesn’t work either. I get the error message, “This block
   has encountered an error and cannot be previewed.” The new page was not cloned
   or copied. It was a new page with only the Alphabetical Tag Index block on it.
 * I’ve run Tag Group’s First Aid function in Tag Groups > Settings > First Aid 
   > Maintenance. It found no errors. 
 * I am at a loss over what to do next. Are these errors familiar to anyone? Thanks.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Ferror-loading-block-invalid-parameters-attributes-12%2F%3Foutput_format%3Dmd&locale=en_US)

 * Hi [@tlinn](https://wordpress.org/support/users/tlinn/). Thanks for using Tag
   Groups. This a common WordPress error that impacts a lot of plugins. Do a quick
   Google search and you’ll find a lot of results for this error. The first thing
   to look for is a possible plugin conflict.

 * Thanks for using Tag Groups. We’ve not heard from in a month so are closing this
   for now. Please post back again if this remains an issue.
