Hello all. Just upgrading an older site (1.5.6c). On apache with php7.4. So I started with fresh subdomain and DB copy from live site (same server cpanel copy over). Uploaded fresh zip, extracted into public then ran the ZC1.5.7c installer and upgraded database. Everything works great with responsive classic template. Installed the most recent boot strap and now the product listings are breaking out of their boxes. Like there's a missing clearBoth somewhere. Before I start digging around. Is there a known issue?

Thank you,
John
