If this template helps then use it. If not then just delete and start from scratch.

**OS** (e.g. Win10): Win 10  
**PsychoPy version** (e.g. 1.84.x): 2020.2.0  
**Standard Standalone? (y/n)** If not then what?: Y

Hi  
**What are you trying to achieve?:** I had an experiment (initially it was designed on psychpy version 2020.1.3, yet it was running with version 2020.2.0) that was running online (I cant sent the url as in correcting project I deleted and now I am not able to create it successfully).  
I added a block and suddenly in the middle it gave few errors screenshot attached.  
Note it is running offline perfectly fine.

**What did you try to make it work?:** I uninstalled PsychoPy and Installed it again. I deleted the project and tried creating it again.

**What specifically went wrong when you tried that?:** I am not sure what wen wrong. now in the latest version also I see the error message.  
Include pasted full error message if possible. “That didn’t work” is not enough information.

the error messages are something like below  
1.

I checked JS code made some corrections. Now experiment is initialising but it is giving another error message inspite of given resources on additional resource tab.  
Also I do not see the resource downloading as earlier it used to turn blue on downloading all the resources.

Please help!
