Thanks for all the good information.

I'm still having the problem, so not sure what is happening ...

ok, I'm going to create a patch for your installation.
what's your current build number?

I guess is this one Security update! (Current version: 170522).

I see this: or 2.67.1 (170626)
when I go to confortupdate, as there is one update pending.

Also "Export results to app" is no longer working not sure if it is related, I guess so ...

You can download your patch here:
comfortupdate.limesurvey.org/patches/lim...te-170522-170626.zip

Just extract it in the root folder of your application (check that it's not unpacked in a folder called: limesurvey-manual-update-170522-170626/ ). Rememeber to backup your installation first (db + files)

Ok, I'm now in Version 2.67.1+170626, I believe is the last, so I can't check now if comfortupdate will work. However, I still can't export to an app.

When I click the export button (after selecting Excel), it brings me to example.org/index.php/admin/export/sa/ex...lts/surveyid/175122#

I'm still having the same problem.

You have an error inside your local installation of LimeSurvey. See:
PHP Error [404]
The system is unable to find the requested action "checkLocalErrors".

Also can't export the data "Export results to app" doesn't work.

We have double checked and the OS has nothing wrong. Other apps, web site, etc., are working fine. Only Limesurvey fails.

I've reinstalled limesurvey, and the issue is the same.

Then I've tried disabling Pagespeed, which we use in all our servers, and bingo!

So if somebody has troubles with limesurvey and is using pagespeed, you shoud include
ModPagespeed off


in your limesurvey virtualhost.

I think Limesurvey developers should take a look into that, it is really surprising that it can't be optimized by pagespeed ...

thank you very much for that feedback.
Maybe you could add an entry about it in the Wiki?

manual.limesurvey.org/Troubleshooting

Done!

thank you very much.
