Check for possible plugin conflicts

[mehadihasan123456]

Some of the plugins (mostly page builders) may conflict with the block editor and can result in patterns not uploading to the WordPress theme. To solve this issue, you need to deactivate and reactivate each plugin and check the issue every time.

To troubleshoot the plugin conflict issue:

Deactivate a plugin.
Try to upload a block pattern to the theme.
Check if the pattern is uploaded or not.
If the pattern is uploaded to the theme cryptocurrency data without an issue, that means the plugin is conflicting with your block editor.

Then you need to contact that plugin developer to address the issue.

On the other hand, if the patterns are still not uploading, then reactivate the plugin and check other plugins similarly.

To avoid possible plugin conflicts, you can use a page builder that is dedicatedly made for Gutenberg blocks. For example, GutenKit is a block editor plugin that brings all the page builder features to Gutenberg with seamless integration with the capability to design a complete website with Full Site Editor (FSE) support.
