Problems after upgrade to 0.3.5

I now have tested to go back to Version 0.3.2 of the plugin and have the same phenomenon it seems that the problems has to do with my wordpress upgrade from wordpress 4.5.2 to 4.6.1

So it looks like it’s not strictly related to the plugin …
have you tried to do a new WordPress installation, install the plugin and import data ?

I tried the following (in my test-environment)
I deactivated all other plugins but still .epub is greyed out in the File-Selection-Dialog für upload
the next try will be a new worpress-installation but i think this will last a few days

I just finished my new test-installation:

wordpress 4.6.1
WP Extra File Types 0.3.5 as only plugin installed and activated
.epub activated in the settings of the plugin

result:

i start to create a new post
click on the button for file upload and
in the file-selection-dialog .epub files are greyed out and not selectable

i’ve just done some test on my WordPress 4.7 :
— Admin – Media – Add New – Upload –> .epub uploaded
— Admin – Posts – Add New – Add Media – Upload Files–> .epub uploaded
— Admin – Posts – Add New – Add Media – Media Library browser–> .epub selected

Could you compare your installation with my screenshots ?

Could you send me the .epub you want to upload just to test the system your file ?

Do you have problems uploading other “extra” file types or just with epub ones ?

in Screenshots 01-07 you see different file-types i activated in the settings

in Screenshots 10 you see the dialog that results when in changing a post or creating a new post i click on the button for file-upload

in this dialog the click on “Dateien ausw?hlen” (file select) results in the file-selection-dialog
the following screenshots show the file-selection-dialog positioned to different of the activated file-types
some are selectable – especially the MS-Office-documents
others are not selectable (greyed out) especially the apple-file types .pages .numbers
by the way: the actual apple-file type for keynotes is not .keynotes, but .key
and the Open-Document-file types as .odt, as well as .epub are not selectable
.jpg is selectable
the actual kindle ebook file type is .azw3 (.azw is an older version)

one of the .epub files i copied in the folder also

my test-installation is with wordpress 4.6.1 – do you think an upgrade to 4.7 could be helpful?

it’s strange … the “input[type=file]” in the page doesn’t set any “filter”, i do not understand why your “Finder” does not allow you to select certain files.

Have you tried using “Drag&Drop” instead of using the upload button ? see file “003-drop.jpg” in my google drive directory.

per drag and drop it worked with .pages and with .epub
it eben worked with .key althoug the keynotes-files appear with .keynote in the settings of the plugin
but now the next phenomenon:

i have deactivated .docx and .xlsx again in the settings but per drag and drop i still can upload them

then i deactivated the plugin itself and even now i can upload all filetypes per drag and drop while still when trying over the file-selection-dialog the same filetypes are selectable and the same appear as greyed and are not selectable

as i recognize now:
in my production environment the plugin must be activated, for uploading the files by drag and drop – so i have a workaround – but it remains strange, that the finder doesn’t show the files as selectable anymore
