Please try adding this chrom extension and check this issue again .
refer : https://chrome.google.com/webstore/detail/allow-control-allow-origi/nlfbmbojpeacfghkpbjhddihlkkiljbi?hl=en 

Also check if all packages are installed ?
refer this unit : https://wplms.io/unit/installing-app-packages/

Did installed the said Chrome extension and reinstalled the same with said commands.

Now I can’t even find my courses in the app.  Only default courses load. Did also went to config.ts and checked for setting. All is fine here.

Any idea why this may be happening?

[Alex]

CAn you please share screenshot or the actual error in browser’s console?

[Mahesh Prabhu]

Sorry for the delayed response. I reinstalled everything and I still get the error (see screenshot 2) and I also wanted to know why do I still get the default courses in the POPULAR COURSES and FEATURED COURSES. Let me know as to how can I change the TITLE in the home page and elsewhere within the app.

Well we are not able to replicate this issue at our end with or without the cors extension enabled .

Please make sure that you are using the latest package of wplms ionic app .

If still issue appears then pleas share your whole ionic project folder in zipped format with us to check this out .(upload it somewhere online and share its link here in private reply ).

To show data from your site you need to clear the existing data first .

refer : inspect element and then : http://prntscr.com/i3rsos

 

 

[Mahesh Prabhu]

Thank you for the reply. The clearing data option worked.

I am now unable to login to the system through my app. Any idea why it be so?

Deeply appreciate your help.

[Alex]

Well app has a localstorage .The featured courses section data is stored once app is opened and it does not changes later .So if initially featured courses was not able to load and then it does not show them later then .

Are still facing issues with imagecache error in app  ?

[Mahesh Prabhu]

I still get a lot of other errors as well when I check other pages. Shall I send you the whole directory zipped? Please confirm will do so.

Can you please share exactly which errors are you facing ?

I tried but it seems your system is on mac or linux . Its not working on windows.

whet you can do is in your project rename “node_modules” folder to “node_modules.bak” and package.json to “package.json.bak” .
Then download package.json file from here : http://bit.ly/2n7mVM7

 

then open terminal or cmd navigate to project folder and simply run this command :

npm install

 

[Mahesh Prabhu]

I don’t get any errors now. Yet I am unable to login to the course from the app with my user name and password – it doesn’t even  give any errors.

I use Windows OS. Not Linux or Mac as you misconstrued.

Let me know if you can help me – or let me have my money back. As this is proving to be a big ordeal.

Ok. Now I am getting the following error. Let me know if you can help.

[Alex]

Well now your environment and my environment is same .  Im not facing this error with your src folder in app .
refer : http://prntscr.com/i59liw

I am running it on chrome ,can you please try this in chrome.

This error might be appearing because of access not control origin restriction set in browser .due to this image cache plugin is not able to download the image from external url and save it on machine .

Hence generating this js error .
