# Possible simple_html_dom_node lib conflict

* Ultimate Blocks” now has “simple_html_dom_node” class renamed to “ub_simple_html_dom_node”
but it does not have functions like “file_get_html” and “str_get_html” renamed.
So even if other plugin checks if class exists, it checks for “simple_html_dom_node”
and it fails to find it so it loads its own version which leads to fatal error
because functions are duplicated.
* Thanks!

* Hmmm, this seems like my error that did break my site after the last auto update
yesterday. Now my EmbedPress can’t run if the Ultimate Blocks plugin is active
too. The error noted “Fatal error: Cannot redeclare file_get_html()” and notes
conflict with EmbedPress. So yeah, update?
