Learn how to detect and remove the dangerous gsyndication.com malware from your WordPress site. Step-by-step guide for cleaning malicious code and preventing reinfection in 2025.

Visitors to your WordPress site see a fake 'Cloudflare verification' page telling them to paste a command into Windows Run or Terminal. That's ClickFix, the social-engineering campaign that first appeared in early 2024 and exploded across compromised WordPress sites by autumn. What it does, where the injection lives in your site, and how to clean it without missing the persistence.

A WooCommerce store slows down for specific, structural reasons. Here is the layered fix: hosting, page caching, object caching, the database, search, and the front end, and why one layer alone is never enough.

MySQL cheat sheet covering CLI commands, database and table operations, joins, indexes, backups, user management, and transactions, with version notes for 5.7, 8.0, and 8.4.

MySQL 8.4 is the new LTS branch, with Premier Support through April 2029 and Extended Support through April 2032. The 8.0 to 8.4 upgrade is much smaller than 5.7 to 8.0, but removed options and the new authentication_policy variable still bite. Full procedure with rollback.

MySQL 5.7 has been past its EOL since October 2023. Here is the migration to 8.0: prerequisites, dry-run with mysqlcheck, in-place upgrade, the authentication-plugin change that breaks old clients, and rollback if it goes sideways.

The grep -o 'pattern' file | sort | uniq -c | sort -rn pipeline is the classic log-analysis one-liner. Why sort must come before uniq, how each stage works, worked examples for top IPs and status codes, the awk one-pass alternative for huge files, and the BSD vs GNU notes.

find walks the live filesystem every time it runs: always current, sometimes slow. locate queries a prebuilt database: instant, but stale until the next updatedb. This breaks down the locate family (mlocate, plocate, slocate), the macOS situation, and exactly when to reach for each one.

grep filters lines, awk extracts fields. The classic pipe is grep 'pattern' file | awk '{print $2}'. This covers awk field basics ($1, $NF), custom separators with -F, multi-column output, the cases grep -o and cut cover on their own, and the fact that awk's own pattern match makes the grep half optional.

macOS ships BSD find; Linux ships GNU find. The two share a name and most of an interface, but -printf, -regextype, and the stat format strings diverge hard enough to break scripts shipped between platforms. The full divergence list, the portable subset that works on both, and how to get GNU find on a Mac.

Every modern way to force a page to the top on browser refresh: window.scrollTo, the scrollRestoration API, React Router ScrollRestoration, Next.js Link scroll prop, and the events that fire on unload. Plus the hydration race that breaks naive implementations.

The application-layer DoS testing tools I actually use in 2026 for resilience and load testing: k6, wrk2, slowhttptest, recheck, h2spec/h2load, Burp Turbo Intruder, Locust, and ZAP. Strengths, weaknesses, and how I pick.

The clickjacking tools I actually reach for in 2026: PoC generators, OWASP ZAP, DNSChkr HTTP Security Headers, Mozilla Observatory, Burp Active Scanner, and the post-Yibelo double-clickjacking PoC repos. Honest framing on a thin tool space.

The CSRF tools I actually reach for in 2026: Burp Suite's PoC generator, OWASP ZAP, xsrfprobe, Param Miner for hidden token discovery, plus the manual Origin and SameSite workflow. Honest framing on a defence class that mostly won.

Increase the PHP memory_limit via php.ini, .htaccess, ini_set(), the -d CLI flag, PHP-FPM pool config, or wp-config.php. Covers the modern PHP 8 defaults, the OPcache caveat, and the Composer/PHPUnit/WordPress out-of-memory patterns.

Drop empty, null, or false values from a PHP array with array_filter and the right callback. Includes the '0 gets removed' gotcha, the array_values re-index pattern, multidimensional cleanup, and a performance comparison.

The Internet Archive plays by different rules than AI or search bots. Here is how to keep new pages out of the Wayback Machine, how to remove pages that are already archived, and what to do when robots.txt is not enough.

I blocked every AI bot I could when they first started slamming my servers. A few months later I unblocked most of them. This is the decision framework I wish I'd had at the start.

The full reference for blocking AI crawlers: which bots matter, what each one does, robots.txt and server-level rules, Cloudflare's managed approach, WordPress paths, and the bots that ignore robots.txt entirely.
