Compatibility issue with OMGF

Hi!

We have a mutual client who is experiencing a compatibility issue between your plugin and OMGF (my plugin).

The issue lies in the usage of output buffering. Speed Optimizer and OMGF both start output buffers with a callback, but since Speed Optimizer flushes all output buffers, OMGF’s callback never runs.

A fix I found would be to add a filter to your output HTML, e.g. at the end of SiteGround_Optimizer\Parser\Parser::run():

	/**
	 * Run the parser.
	 *
	 * @since  5.5.2
	 *
	 * @param string $html The page html.
	 *
	 * @return string $html The modified html.
	 */
	public function run( $html ) {
		if ( ! preg_match( '/<\/html>/i', $html ) ) {
			return $html;
		}
		
		// Replace unsecure links if the option is enabled.
		if ( Options::is_enabled( 'siteground_optimizer_fix_insecure_content' ) ) {
			$html = Ssl::get_instance()->replace_insecure_links( $html );
		}
		
		// Do not run optimizations if amp is active, the page is an xml or feed.
		if (
			$this->is_amp_enabled( $html ) ||
			Helper::is_xml( $html ) ||
			is_feed()
		) {
			return $html;
		}
		
		// If the user is logged in and the filebased caching is disabled.
		if ( is_user_logged_in() ) {
			// Return the original html if the filebased caching is disabled.
			if ( ! Options::is_enabled( 'siteground_optimizer_file_caching' ) ) {
				return $html;
			}
			
			// Return the original html if loggedin filebased caching is disabled.
			if ( ! Options::is_enabled( 'siteground_optimizer_logged_in_cache' ) ) {
				return $html;
			}
		}
		
		$optimized_html = $this->optimize_for_visitors( $html );
		
		if ( Options::is_enabled( 'siteground_optimizer_file_caching' ) ) {
			File_Cacher::get_instance()->process( $optimized_html );
		}
		
		return apply_filters( 'sgo_optimized_html', $optimized_html );
	}

With this filter in place, OMGF would hook into that, so it could still apply its optimizations, e.g.:

		if ( defined( 'SiteGround_Optimizer\PLUGIN_SLUG' ) ) {
                        remove_filter( 'omgf_buffer_output', [ $this, 'process' ] );
			add_filter( 'sgo_optimized_html', [ $this, 'process' ] );
		}

Hopefully you’d be willing to add this filter short term to help out our mutual client.

Looking forward to your reply!

Kind regards,
