angstrom on "woocommerce causing errors"

Thanks laliz,
I temporarily set wp_debug to "true" to see & print errors. I can't look at error.logs for some reason. My error list refers, for example, to "undefined variable: control ops in directory path .../wp-content/themes/rentmothernature/functions.php on line 35". I have 7 of those for front end of site -2 of which -line 162 & 185- also appear in back-end dashboard (/admin).
I will look further into this.
