Error on saving edits

Permalink
Hi everyone, we're using concrete 8.3.2, we were using the CMS fine before, but since we setup or website on cloudflare we started having trouble saving edits.
When we edit some blocks, like the navigation for example, it returns the following error when attempting to save the changes on the block level.
if (!$arHandle) { $arHandle = $request->request->get('arHandle'); } $bID = $request->query->get('bID'); if (!$bID) { $bID = $request->request->get('bID'); } $a = \Area::get($this->page, $arHandle); if (!is_object($a)) { throw new \Exception('Invalid Area'); } $this->area = $a; if (!$a->isGlobalArea()) { $b = \Block::getByID($bID, $this->page, $a); $this->set('isGlobalArea', false); } else { $stack = \Stack::getByName($arHandle); $sc = ConcretePage::getByID($stack->getCollectionID(), 'RECENT'); $b = \Block::getByID($bID, $sc, STACKS_AREA_NAME); $b->setBlockAreaObject($a); // set the original area object $this->set('isGlobalArea', true); } if (!$b) { throw new Exception(t('Access Denied')); } $this->block = $b; $this->permissions = new \Permissions($b); $this->set('bp', $this->permissions); $this->set('b', $b); } public function getViewObject() { if ($this->permissions->canViewEditInterface() && $this->canAccess()) { return \Concrete\Core\Controller\Controller::getViewObject(); } throw new Exception(t('Access Denied')); } protected function getBlockToEdit()


We're not absolutely sure if these errors are cloudflare related. Is anyone else having these weird errors? What could possibly cause this if not cloudflare?clo
