xPDO.php line 667

  $this->log(xPDO::LOG_LEVEL_ERROR, "Could not load class: {$classname} from {$fqn}");

modParser.php : 512 (I have no snippet named “id”)

  $this->modx->log(xPDO::LOG_LEVEL_ERROR, "Could not find snippet with name {$tagName}.");

Do you have the extra Articles installed (and in use)?
It could be that the class_key of the Articles resources wasn’t updated for MODX 3 (when you switched from MODX 2 to MODX 3).

It’s not a problem with pdo.
xPDO just can’t load a custom class that’s not available.

You get the “Could not find snippet with name” error message everytime the MODX parser finds a snippet tag (in a resource or chunk) it can’t process.
E.g. a tag like [[!whatever]] (or [[whatever]]) generates the error “Could not find snippet with name whatever.”

Here the code tries to find a snippet with the name
'id', '567acf50abe53d964f8310ac'], ['mark', 'firstbyte', (new Date()).getTime()

Sometimes when you have data with nested arrays (e.g. [['a','b'],['c','d']]) on a page, the MODX parser thinks it’s a snippet (because of the [[ and ]]) and tries to parse it. This is likely the case here. Try to add spaces between the square brackets (e.g. [ ['a','b'],['c','d'] ]) if possible.

Yes had Articles installed and just RE-installed it. Ok will investigate further, Thanks

Resolved. Had a pingdom embed causing it in the template
