Plugin causes issue with wpml 4.9.3+

Hi

The plugin causes a conflict with the latest wpml version. the content in posts and pages is gone when using anchor links.

By adjusting the code on line 79 to

add_filter( 'the_content', 'AutoAnchor_add_anchors_to_headings', 99 );

Everything is working again.

Please adjust the plugin.

Thank you
