WCPDF output blank PDF when Weglot plugin is active

Hi team,

I’m experiencing a compatibility issue between the Weglot plugin and the WooCommerce PDF Invoices & Packing Slips plugin when using the Dompdf engine. Problem:

When Weglot is active and a user accesses the invoice PDF from the My Account page in a non-default language, the generated PDF is completely blank. The same invoice renders correctly in the default language or when Weglot is disabled. Debugging so far:

• Disabling Weglot resolves the issue immediately.
• Commenting out the following lines in bootstrap.php of the Weglot plugin also fixes it:

// '\WeglotWP\Third\Woocommercepdf\Wcpdf_Active',
// '\WeglotWP\Third\Woocommercepdf\WCPDF_Weglot',

• However, commenting out the actual translate_pdf() logic inside those classes has no effect — the PDF still renders blank.
• I enabled Dompdf debugging (debugCss, debugLayout, logOutputFile) — the logs indicate no layout is processed at all.
• The HTML being passed to Dompdf is valid and works fine when Weglot is inactive.
• This behavior occurs only when accessing the PDF from My Account in a translated language. From the admin area or default language, the PDF renders as expected.

It appears the presence of the Weglot integration classes alone — even without actively modifying the PDF content — disrupts Dompdf rendering when language is switched from the site default. Possibly due to output buffering, encoding, or unexpected side-effects in filters.

Would appreciate your insight or a recommended fix/workaround.

Thanks in advance!
