 * Hi [@vladav](https://wordpress.org/support/users/vladav/),
 * Thank you for reaching out.
 * This type of error can occur if one of the translated strings in Loco Translate
   is incomplete or if the formatting placeholders have been modified during translation.
 * Could you please search for the following string in your Loco Translate file?
 * `%1$sthis doc%2$s`
 * We recommend keeping this string exactly as it is, including the placeholders(`%
   1$s` and `%2$s`), as they are required by the plugin. If the translation is incomplete
   or the placeholders have been changed or removed, it can trigger the **“Unknown
   format specifier”** error you’re seeing.
 * After restoring the string, please save the translation and check whether the
   error is resolved.
 * If the issue persists, please let us know, and we’ll be happy to investigate 
   it further.
 * Thank you
