PrestaShop Web Design
Technical notes from live stores: upgrades, speed, SEO, malware and multilingual Shopify. Written from production, not from a demo install.
Actionable write-ups on speed, SEO, security and upgrades. English originals of the same production cases documented on the Spanish blog.
Live case on colchoneriasgonzalez.com: mobile PageSpeed Insights from 71 to 90. LCP 3.4 s, CLS 0. What not to touch on Hummingbird.
Read articleOn colchoneriasgonzalez.com/blog the dashboard loaded as raw HTML while login still had CSS. The concatenated load-styles.php URL returned 403. The fix was in wp-config.php.
Read moreOn colchoneriasgonzalez.com, Merchant Center hid the catalogue for misrepresentation. Placeholders, contradictory shipping, a missing tax ID in the footer, and a dirty feed had to be aligned before requesting review.
Read moreOn comastrial.com, PrestaShop 1.6.1.24 loaded the login page with an empty centre column. AuthController.php contained malware and returned before setTemplate. Surgical restore — and a reason to leave 1.6.
Read morecolchoneriasgonzalez.com moved to PrestaShop 9.1.4 on Plesk. The work was collation, an nginx 403 on the renamed admin folder, and Twig cache after cutover — not a one-click upgrade.
Read moremadridhiking.com sold, but Spanish URLs opened English content and Hypershell landings had no SEO. Theme, language routing and metadata had to be fixed together.
Read moreOn irepairphone.es/blog the owner saw a “virus” and the home showed hidden Premier League betting spam. Cause was theme plus a fake plugin, snippets and users — not one checkbox.
Read moreOn colchoneriasgonzalez.com, PrestaShop 1.7.8.3 froze in the back office when editing products with hundreds of combinations. The useful fix was a PHP input limit, not a new theme.
Read morePrestaShop 9.1.3 can keep the State dropdown on A Coruña when editing addresses. No red error. The cause is data/locale in the address form, not the customer “doing it wrong”.
Read morereparacionmovil.es on PrestaShop 9 returned HTTP 500 with no useful message on the storefront. The log, not a theme swap, showed what to revert.
Read moreA slow PrestaShop store loses sales and crawl budget. Measure the templates that sell, cut module and image weight, configure cache, and check checkout on a real phone.
Read moreWell-built PrestaShop categories capture commercial searches. Titles, unique copy, filters and canonicals matter more than stuffing product meta tags.
Read moreUpgrading without a plan takes the store down. On gsmsofia.com the path from PrestaShop 1.6.4 toward 9 used staging, B2B data checks and order tests — not a production one-click.
