@kamatozzz:
Try delete and install WassUp plugin again. A file may have been corrupted during your last update.
If the problem persists, then an error message is being printed before WassUp writes it tracking cookie. Look at the ‘view source’ in the document where this error occurs. <!DOCTYPE html> should be the 1st line. If it is not, read the message above it. If it is from WassUp plugin, please paste it here. If it is not from WassUp plugin, go to the appropriate forum for your answers and/or deactivate the problem plugin.
