\n Quick Answer:<\/strong> To increase the phpMyAdmin upload file size limit from the default 2MB to 512MB+, adjust 4 core PHP directives in your active php.ini<\/code> file: set upload_max_filesize = 512M<\/code>, post_max_size = 512M<\/code>, memory_limit = 512M<\/code>, and max_execution_time = 300<\/code>. In cPanel, navigate to Select PHP Version > Options<\/strong> or MultiPHP INI Editor<\/strong> to apply these values in 1-click.\n <\/p>\n

Why Does phpMyAdmin Default to a 2MB Upload Limit?<\/h2>\n

By default, vanilla PHP installations restrict file uploads to 2MB (upload_max_filesize = 2M<\/code>) to prevent unauthorized users from exhausting server memory buffers during HTTP POST requests. However, modern WordPress databases with years of blog posts, WooCommerce transactions, and page builder data routinely exceed 50MB to 500MB, triggering the frustrating “No data was received to import”<\/em> or “File exceeds maximum allowed size”<\/em> errors in phpMyAdmin.<\/p>\n
