Footer and Logo preview not updating

Question

I am trying to upload the logo to the Header of my survey. I have uploaded the logo successfully (via the logo tab of the Footer and Logo page) and the image file meets the criteria for the image (i.e. .png and 140px wide). However, I encounter the following problems:
1) the preview of the logo (with the Lorem Ipsum text) below does not update
2) the logo is not updated on the pretest/preview version of the survey.

Any support on how to proceed would be much appreciated, the logo is the last hurdle before being able to publish and collect data on my survey.

Many thanks in advance.

Answer 1

1) the preview of the logo (with the Lorem Ipsum text) below does not update

Please make sure to write/copy the contact information in the upper field, the form with the details is only an assitant to create the HTML code.

2) the logo is not updated on the pretest/preview version of the survey.

Most likely this is a client-side caching issue. Please empty the browser cache or tell it to reload the images on the page.

Dear SoSci Survey,
Thank you for your rapid response.

Regarding query 1) the HTML code is up to date, this works fine in the preview and in the live version of the survey.

Regarding query 2) about the logo not updating. I have cleared the cache of the web browser (Microsoft Edge), I  have updated the logo again and also tried to hard refresh the page (Ctrl + Shift + R) also with clearing the cache. In this case, I recieve an error message:
"Error: The server was unable to validate that you actively triggered the action. Please confirm that you are working on the right project and double check the data. If everything is fine, please submit, again."
I control that that project is accurate and I upload the logo again and press the "Save" button, but it still does not update the Preview below (or the live survey).

I have tried on a Chrome web-browser and experience the same behaviour, including the same error message.  

I am happy to share screenshots of the error messages should this help troubleshoot the issue.

Hmm, you're not working on www.soscisurvey.de, is that right?

I did not have the logo issue that you describe so far, so I cannot offer a trivial solution. We'll have to try a few things. First, when you select to use no log, save, than change back to the custom logo (doing a new upload), what happens?

Second, please check the menu "images and media files" and look fo the logo. Can you delete the logo there?

I am working on an instance of SoSci Survey that is hosted by my university.

When I select "no logo" and save, the standard SoSci logo does not go away from either the preview or the live survey. When I then upload a new custom logo, the logo updates in the "currrent logo" view on the right hand side, but does not update in ther preview below, or in the live version of the survey.

Yes, I am able to delete all instances of the logo from the "images and media files". When I delete all logos here, the Logo section in the "Footer & Logo" tab automatically defaults to "Default logo".
