Yacapaca crashing Internet Explorer.

[Yacapaca]

FN-GM, do either of the following help? I strongly suspect you will have done both already, but who knows....

1. Add yacapaca.com to the Allowed List for cookies
   
2. Add https://yacapaca.com to the Trusted Sites list. Note no 'www.' here.
   

 

There is also a theoretical possiblity that the particular quiz you are testing contains a corrupted image or sound file that is tripping you up. Which specific quiz have you seen the problem on? What happens if you try a quiz from a completely different course? Or one that has no sound or image files? It's highly implausible that this could be the cause, but then we have eliminated all the plausible reasons already.

 

A final thought: you could use Fiddler to inspect exactly what was happening just before your browser crashed, then send the log to us for analysis. I have not used it myself, but have seen it recommended.

Hello Yacapaca,

 

We are currently experiencing problems using your web based test. The following error message prompts when two or more students try to use the service - 'Flash has detected a problem on the network. Please check your internet connection has it appears to be running very slowly'.

 

I have to say our internet connection is a 100mb link and with a class of 30 trying to use Yacapaca, it only utilised 13% of this bandwidth, so hardly a bottle neck issue.

 

Please find attached a screenshot of the error message.

 

We have tried in different classrooms and computers but still same result.

That's the trouble with error messages. Half the time they point completely the wrong way. All that Flash really knows is that the download timed out. It has no way of knowing why.

 

Copied from: Quizzes get stuck whilst loading - Yacapaca wiki

 

Quizzes can get stuck whilst loading for a lot of different reasons. Most of them can be summed up in two words: Internet Explorer. Switch to Firefox or any other modern browser, and your problems will most likely go away. Assuming that is politically impossible, work your way down this list of possibilities and you will probably be able to resolve the problem.

 

* the Group Policy is blocking some Yacapaca functions on student computers. This can result in all kinds of weird, intermittent behaviour. If you use Microsoft products on your network, do these first:

o Add yacapaca.com to the Allowed List for cookies.

o Add https://yacapaca.com to the Trusted Sites list. Note no 'www.' here.

 

* the school's proxy server or filter is blocking images or (particularly) sound files such as MP3s. If this is the case, you will still be able to load quizzes containing only text.

 

* same as above, but the ISP's filter. We have never seen this with commercial ISPs, only Local Authorities, Grids for Learning, Broadband Consortia, etc.

 

* Flash needs re-installing on the problem machine. Flash can be a bit fragile, and sometimes simply reinstalling solves the problem. Typically affects individual computers, not a whole room-full.

 

* the school's network has stalled or is temporarily overloaded. This should only affect you very briefly. If you are stuck in front of a 'loading' icon for over a minute, it is definitely not this.

 

* if one particular quiz refuses to load even on your home computer, but all others load with ease, there may be corruption in the quiz file. Unless you are the author, report it to us.

I can't think of a GPO which can do this, but an easy test would be to logon locally to a machine (as an administrator) and repeat the same test using the same internet connection. If the problem still exists, the probability is that it isn't a GPO problem.

I have to agree, most Authorities use proxy servers these days and but at times they can most definitely be more trouble than they're worth.

 

Flash needs re-installing on the problem machine. Flash can be a bit fragile, and sometimes simply reinstalling solves the problem. Typically affects individual computers, not a whole room-full.

 

Deploying the latest MSI is the easiest/best way forward. You can download the MSI and other plugins within the File Library.

 

the school's network has stalled or is temporarily overloaded. This should only affect you very briefly. If you are stuck in front of a 'loading' icon for over a minute, it is definitely not this.

 

Possible however I'm sure they'd be many, many more important problems to fix

 

if one particular quiz refuses to load even on your home computer, but all others load with ease, there may be corruption in the quiz file. Unless you are the author, report it to us.

 

I would say this is more than likely the reason(s) for crashing or loading incorrectly. The proxy copy could be corrupt or indeed the local cache on the machines too. Very difficult to pin down, but then again, I presume you have a testing process before publishing new quiz files?

Hi,

 

ICT are using a site called Yacapaca. Its a site used to test the students.

 

It is crashing IE7 & 8 half way through a quiz. It might be a group policy issue but its hard to drill down as it is very Intermittent.

 

Has anyone else has trouble with this site?

 

Thanks

 

Yes, we also have IE7 and are getting it crashing sometimes. Other times it is fine. I currently have Flash 10.1 (the latest version) happily installed, but with YacaPaca is sometimes crashes. Are there any solutions have appeared in the year or so since this thread was created?

Nope, they dont use it anymore thank god.

 

We eneded up using chrome and it worked fine in that.

The distilled wisdom on the subject is here. Group Policy seems to be the most usual culprit; I would advocate Michael's test: "logon locally to a machine (as an administrator) and repeat the same test using the same internet connection. If the problem still exists, the probability is that it isn't a GPO problem." Assuming you can't follow FN-GM and switch to Chrome.
