It's a fantastic suggestion. Thx.
I thought this contrib have some function what cooperate with the Header Tag SEO and an advanced user can tell me were are this codes exactly, and I put an symple if statement (If HEADER_TAGS_INSTALLED==True Then...) before this functions...
I touhgt is easier than I downgrade or uninstall or anything else...
I don't understand why develop this contrib on two lines (with or without Headar Tags)...
Sorry for the question...
