Error"Reload the page to log in" is shown when try to insert any items to the page in Mahara 17.10.x version using IE 11 under Window 10 Enterprise (64 bit)

Dear ,
We upgraded Mahara to 17.10.x version and PHP is also upgrade to 7.0.x
When I try to IE 11 browser under window 10 Enterprise (64 bits) OS to edit the page by adding some items e.g. Text block to the page (please see the following screenshot).
IE version
IE 11
11.431.16299
11.0.65
Error "Reload the page to log in" is shown and cannot insert the image block to the page.
While I do the same tasks using Google chrome or Firefox under OS, it is okay and no problem is found.
It seem it is relevant to IE 11 under Window 10 OS .
Then I try to another PC which installed with IE 11 under Window 7 (64 bit). It is also okay and can add the image block to the page.
In apache error log, it show below error

Hi William,
I believe the problem you are getting relates to this line of the error report
ArtefactTypeViewoutcome::render_self() should be compatible with ArtefactType::render_self($options)
In PHP 7+ a method in a child class needs to have at least the same parameters as the parent method.
So the Artefact plugin Viewoutcome render_self() function needs to have the $options parameter
As the Viewoutcome plugin is not part of core you can try and fix up yourself.
See https://reviews.mahara.org/#/c/6408/ for changes done to various artefact / blocktype plugins to make them PHP 7 compatible
Cheers

Dear Robert,
Thank for your reply.
I remove "outcome" plugin from the system.
Still have same problem.
I further investigate it. I find the root cause is that the uploaded pdf cannot be shown properly using IE 11 with Window 10 in our office environment. ("Invalid or corrupted PDF file). Then after I try to insert image block to the page. The error is shown and cannot add any block.
While I use my home PC or notebook with same window OS to test it . The PDF can be shown properly and I can insert any block to the page.
There is no problem if using Google or Firefox browser.
Any Hint?
Regards,
William

Dear ,
After further investigation, we find the root cause is that
In our office environment, All Office PC are added to the window Domain and customized group policy is enforced in all office PC.
For the IE security setting in Group policy, we add only some sites are trusted.
we find there is cross domain issue when loading PDF.js to load the pdf file from mahara page.
When we set IE security setting from group policy to trust all site.
PDF file can be loaded correctly in IE 11 under Window 10 in our office.
I think there is some external site to call in PDF.js.
Becuse of cross domain and non-trusted site , the PDF.js cannot be loaded successfully.
Please advise how to do it.
Solution Option 1) modifiy the pdf lib files in Mahara to not load external site.
Solution Option 2) add external site loaded from PDF.js to the trustful site list via group policy.
Please advise.
William
