Thumbnails no more crated

Ok, thanks. Some days ago I purchased the upgrade to VB5 Connect. In the next days I'lll purchase the professional upgrade service. I think this will fix the problem.

What is the output of the File Upload diagnostic under Maintenance -> Diagnostic. Though I heavily suggest upgrading to least vBulletin 3.8.11 and PHP 7.1 more up to date PHP libraries, including GD.

Sorry for my delay.
The processing library is GD

What is the Image Processing Library set to under Settings -> Options -> Image Settings?

What is the result of clicking on the link for "Not OK" in your screenshot? Do you get the image or an Invalid URL error?

I get the image, not an invalid URL error.
When I add an attachement to the post, it is regularly uploaded, but the thumbnail is not created. The thumbnail is created only if the uploaded image is very small. This started happening from early February for no apparent reason.

If an attachment no longer exists, it can provide a link like that.

Thanks for answer. The server is running under PHP 5.4.45. I know that version3 is now end of life, but until a few days ago, thumbnails were created without problems. Is it the beginning of the end ? Any suggestions on what I might check ?

What version of php is your server running on?

vBulletin 3.8.6 will not work with later versions of php. I think it will need to be php 5.3 or below for 3.8.6.
vBulletin 3.8.11 will run php up to version 7.1.
Beyond that, vBulletin 3 is now end of life so the support we can provide may be limited by that.

just to explain better the problem, I add the picture in attachment

HI,

as of a few days ago my forum ( www.hamradioweb.org/forums under vbulletin 3.8.6) no longer creates thumbnails of graphic attachments. This appears to happen if the attached file exceeds a certain size (very small). But until a few days ago thmubnails were created without problems. There were no changes in the forum setup. What could be the problem ?
