[Решено] Fatal Error

Problem:
After installing the WPML plugin and activating languages, everything works except when logging in as an administrator, which triggers a fatal error. The error message indicates an issue with DOMDocument::loadHTML() due to an empty argument in the WPML String Translation plugin.
Solution:
We recommend two approaches to resolve this issue:
1. Disable automatic string registration by navigating to WPML → String Translation and turning off the “Auto register untranslated strings” option.
2. Apply a manual fix in the plugin. Navigate to: wp-content/plugins/wpml-string-translation/StringTranslation/Infrastructure/StringHtml/Repository/HtmlStringsRepository.php and update the function

readAllRawGettextStringsFromHtmlScriptTags

as follows:

private function readAllRawGettextStringsFromHtmlScriptTags( \DOMDocument $dom, string $html ): array {<br />    // We cannot read here with xpath - script tags contain code from the JS template engines and some html will be broken.<br />    // (For example some elements will miss closing tags).<br />    $pattern = '/<script.*?type="text\/(?:html|template)".*?>([\s\S]*?)<\/script>/i';<br />    preg_match_all( $pattern, $html, $matches );<br />    $scriptHtmls = [];<br />    foreach ( $matches[1] as $match ) {<br />        if (!empty($match)) {<br />            $scriptHtmls[] = $match;<br />        }<br />    }
