Seo4Evo and ModX Evo 1.4.3 - swears at "&" in mm_rules - how to fix it?

Question

MODX

There is a site on MODX 1.4.3 and PHP 5.6. There is a Seo4Evo plugin to manage SEO. It includes changes to mm_rules. The site swears at them

//Seo tab
mm_createTab('Seo','Seo', '', '', '', '600');
mm_moveFieldsToTab('CustomTitle,MetaDescription,MetaKeywords,CanonicalUrl,Aliases,GoogleAuthor,RobotsIndex,RobotsFollow,sitemap_exclude,sitemap_changefreq,sitemap_priority', 'Seo', '', '');
mm_widget_tags('MetaKeywords'); // Give blog tag editing capabilities to the 'MetaKeywords' TV
mm_ddMaxLength('MetaDescription', '', '', 350);
mm_ddMaxLength('CustomTitle', '', '', 70);

A simple error is syntax error, unexpected '&' in eval()'d code on line 14. Seo4Evo is the latest, as is ModX Evo. There are no changes in S4E, as well as in mm_rules (except for these).
