Why WordPress causes problems

WordPress powers over 40% of the web, but its flexibility is also its weakness. Third-party plugins, poorly coded themes and automatic updates create fertile ground for bugs.

A fragile ecosystem

WordPress relies on thousands of plugins and themes built by different developers. Every update to WordPress, PHP or a plugin can trigger a chain of incompatibilities. A single outdated plugin is sometimes enough to bring down an entire site. Without regular maintenance, security vulnerabilities pile up and performance degrades over time.

Errors that are hard to diagnose

Unlike a structured framework, WordPress stacks layers of code: core, parent theme, child theme, plugins, mu-plugins and configuration files. When a bug appears, pinpointing the exact source requires deep expertise. Error messages are often cryptic, logs are insufficient and conflicts between extensions are invisible at first glance.

Our WordPress interventions

A rigorous four-step process to identify, understand, fix and future-proof the solution on your WordPress site.

Full audit

We analyse your WordPress site in depth: core version, installed plugins, active theme, PHP configuration, database health and server logs. This audit gives us a complete picture of your environment and helps us spot weak points before even investigating the reported bug.

Precise diagnosis

Based on the audit, we isolate the exact cause of the problem. Plugin conflict, faulty theme, slow SQL query, exploited security flaw or server misconfiguration: every hypothesis is tested methodically. You receive a clear report explaining the root cause and the recommended solution, along with a transparent quote.

Targeted fix

Once the quote is approved, we work directly on your site. The fix is applied in a staging environment when possible, then deployed to production. We test every change across multiple browsers and devices to ensure no side effects are introduced. Your site returns to normal operation.

Follow-up and prevention

Once the fix is applied, we provide concrete recommendations to prevent the issue from recurring: updates to schedule, plugins to replace, configurations to harden. Your WordPress site is in good hands.

Our WordPress technical expertise

Since 2017, we have built deep knowledge of the WordPress ecosystem. From the CMS core to the most popular plugins, including page builders and WooCommerce, we master the inner workings of WordPress. This expertise allows us to diagnose quickly and fix efficiently all types of issues.

Frequently asked questions about WordPress troubleshooting

The initial diagnosis is completely free: we analyse your problem and identify the cause at no charge. The cost of the fix then depends on the nature of the bug. Simple fixes (plugin conflict, configuration error) start from a few tens of euros. More complex issues (hacked site, migration, partial rebuild) receive a detailed quote. You know the exact price before any work begins, with no hidden fees.

The White Screen of Death is one of the most common WordPress bugs. It is usually caused by a faulty plugin, an incompatible theme or a PHP memory limit being reached. While waiting for our intervention, you can try disabling your plugins via FTP by renaming the wp-content/plugins folder. But the simplest approach is to open a ticket with us: we diagnose the cause for free and restore your site quickly.

Yes, cleaning hacked WordPress sites is one of our specialities. We perform a full security audit to identify all infected files, hidden backdoors and the original vulnerability. We clean every compromised file, update WordPress and vulnerable plugins, and install reinforced protections (web application firewall, file monitoring, enhanced authentication). Your site is restored and secured for the long term.

Absolutely. WooCommerce is the most widely used e-commerce solution in the world and we master it thoroughly. We fix cart bugs, payment issues (Stripe, PayPal), stock errors, shipping problems and WooCommerce plugin incompatibilities. We also optimise your store's performance to handle high traffic without slowing down.
