Well I can not access the dashboard plugin, it loads indefinitely. I contacted the plugin of this one and he told me that the problem came from your Haru Myha Core plugin. You can access my website (there are the accesses on other posts that I opened) to see the problem if necessary.
Thanks for your patient!
We found the issue.
You can fix it by go to:
wp-content/plugins/haru-myha-core/ then open file haru-myha-core.php
Go to line 99 and change the code from wp_enqueue_script( $this->prefix .'-select2', plugins_url( PLUGIN_HARU_MYHA_CORE_NAME.'/admin/assets/plugins/jquery.select2/select2.min.js'), array( 'jquery' ), $this->version, false );
