Encountered an installation where a chartset other than UTF8 was used which was causing problems with get_option() (using maybe_unserialize()) from WordPress. The serialized string wasn't correct anymore and returned false causing DB storage not to function properly anymore.
Look into how to convert to JSON:
Find possible issues with older PHP versions
maybe_json_decode method (see below) = PHP 5.3+ > major release only
