Hi,it seems that minify is not able to minify your site clientlib. When the algorithm used by AEM (yui compressor) is not able to minify a javascript inside your clientlib the clientlib.min is not created so you get a 404.You need to test your javascript with the following link [0] in order to find ...

Are you using AEM from a Dispatcher?If yes, you need to be sure that dispatcher is configured in order to allow pass of csrf-tocket header and filter allow the following path /libs/granite/csrf/token.jsonOtherwise token taked with the token.json is not sent to AEM.

Hi,you can do this just only inserting "new line" inside property. Without any special character but only using your submit button.I've tried it in AEM 6.2 and it works.

Hi,are you using jquery from AEM or custom jquery?I think this could be a problem related to csrf token.If you are using custom jquery you need to add a dependency to granite.csrf.standalone clientlib, in order to avoid 403 from AEM [0].[0] https://docs.adobe.com/docs/en/aem/6-2/develop/security/csr...

I've a similar issue, but i fix it just creating a new clientlibrary named custom.authoring.dialog and including it by using extraClientLibs in our components.

I think it depends on different variables. If you have a lot of content, starting from a new instance means that you need to upload all contents and asset and this task could take more than 2 day, so if your customer is not able to wait for more than 2 days this solution is not applicable.

Tested in AEM 5.6 with SP2.You can use the OOTB functionality.It's necessary to select (from damadmin) the asset that you want to check and select -> tools -> references. In this way you can see if the image is used and in which pages.The screen below:

It's the same, you need to click on the components and select the icon on the action toolbar on the components (the last button on right).I attach here the screen, let me know if you have some other kind of problem. 

Probably you have all launcher disabled in the past and for this reason you can uploaded it.But as i already say the exe is not supported.https://docs.adobe.com/docs/en/aem/6-1/administer/content/assets/assets-formats.html

here the docs related to your AEM version https://docs.adobe.com/docs/en/aem/6-1/administer/content/assets/assets-formats.html
