I can confirm I have the same problem; I recently upgraded from NC 10.0.5 to NC 11.0.3 and I also get the "Loading Circle" displayed. Everytime I try an entry is added to the global logfile:

{"reqId":"1GKTSTOZh8Pqj8hws8Cf","remoteAddr":"","app":"index","message":"Exception: {"Exception":"Error","Message":"Call to a member function format() on boolean","Code":0,"Trace":"#0 \/var\/www\/nextcloud1103\/apps\/logreader\/lib\/Controller\/LogController.php(133): OCA\LogReader\Log\LogIterator->current()\n#1 \/var\/www\/nextcloud1103\/apps\/logreader\/lib\/Controller\/LogController.php(73): OCA\LogReader\Controller\LogController->responseFromIterator(Object(OCA\LogReader\Log\LogIterator), 50, 0)\n#2 [internal function]: OCA\LogReader\Controller\LogController->get(50, 0)\n#3 \/var\/www\/nextcloud1103\/lib\/private\/AppFramework\/Http\/Dispatcher.php(160): call_user_func_array(Array, Array)\n#4 \/var\/www\/nextcloud1103\/lib\/private\/AppFramework\/Http\/Dispatcher.php(90): OC\AppFramework\Http\Dispatcher->executeController(Object(OCA\LogReader\Controller\LogController), 'get')\n#5 \/var\/www\/nextcloud1103\/lib\/private\/AppFramework\/App.php(114): OC\AppFramework\Http\Dispatcher->dispatch(Object(OCA\LogReader\Controller\LogController), 'get')\n#6 \/var\/www\/nextcloud1103\/lib\/private\/AppFramework\/Routing\/RouteActionHandler.php(47): OC\AppFramework\App::main('OCA\\LogReader\\C...', 'get', Object(OC\AppFramework\DependencyInjection\DIContainer), Array)\n#7 [internal function]: OC\AppFramework\Routing\RouteActionHandler->_invoke(Array)\n#8 \/var\/www\/nextcloud1103\/lib\/private\/Route\/Router.php(299): calluser_func(Object(OC\AppFramework\Routing\RouteActionHandler), Array)\n#9 \/var\/www\/nextcloud1103\/lib\/base.php(1010): OC\Route\Router->match('\/apps\/logreader...')\n#10 \/var\/www\/nextcloud1103\/index.php(40): OC::handleRequest()\n#11 {main}","File":"\/var\/www\/nextcloud1103\/apps\/logreader\/lib\/Log\/LogIterator.php","Line":75}","level":3,"time":"April 25, 2017 15:07:56","method":"GET","url":"/index.php/apps/logreader/get?offset=0&count=50","user":"admin","version":"11.0.3.2"}

The page gets stuck and does not show anything.
