Error 0 - 3 arguments are required, 2 given

This error is caused by an outdated language pack, more precisely, it is caused by the HTML links added from the following language strings:

  • COM_RSSEO_CHECKPAGE_METATITLE_DUPLICATE_YES
  • COM_RSSEO_CHECKPAGE_METADESC_DUPLICATE_YES

File in question:

/administrator/language/nl-NL/nl-NL.com_rsseo.ini

Important! We release products in English only, the rest of the language files are collected from our translators on the Crowdin platform and may not be up to date.
Solutions

1. We have already fixed this in the language packs from our website, so you can download your language pack one more time and install it over the current version.

2. Remove the anchor tags and their content from the language constants mentioned above, so instead of (for the Dutch language pack):

you will have:

  • COM_RSSEO_CHECKPAGE_METATITLE_DUPLICATE_YES="Deze pagina titel is al %s keer gebruikt. Alle pagina's op uw website zouden unieke pagina titels moeten hebben."
  • COM_RSSEO_CHECKPAGE_METADESC_DUPLICATE_YES="Deze pagina meta omschrijving is al %s keer gebruikt. Alle pagina's op uw website zouden unieke pagina meta omschrijvingen moeten hebben."
