[CMSMS version is actually 1.11.7 but there is no option for that in drop down]

Sadly the retirement of Twitter API v1 today has broken this plugin.  :(

Retirement info:
https://dev.twitter.com/blog/api-v1-is-retired

{$tweets|var_dump} now gives:
array(1) {
  [0]=>
  object(stdClass)#132 (5) {
    ["text"]=>
    string(0) ""
    ["date"]=>
    string(10) "last month"
    ["img_url"]=>
    NULL
    ["author"]=>
    NULL
    ["author_url"]=>
    NULL
  }
}
