REPRO STEPS:

1. Log into self-hosted Wordpress site w/ LBRYPress Plugin
2. Create a New Post
3. Enter 10000 characters into the Excerpt
4. Publish the Post

Results: Post does not publish on LBRY

Expected: Post publishes on LBRY, or user receives an error in the Wordpress UI

Reproduce the 10,000-character Excerpt case in a self-hosted WordPress site with the LBRYPress plugin, then inspect the publish flow alongside the lbrynet console output and the listed RPC call stack. Done means the post either publishes successfully or the WordPress UI reports the failure instead of silently failing.
