I get the above error while trying to Activate Caldera Forms plugin that was installed through the Add New Plugins dashboard. Several other similar plugins also trigger this error: Ninja Forms, Forminator, Everest Forms.

Strangely, other form plugins install and activate normally: CaptainForms, Formidable Form Builder, WP Fluent Forms

I’m using this software:
WordPress 5.3.2

Additional information:
All I’m trying to do is to find a free forms plugin that allows File Upload feature.

Try to install via FTP:

Uploading what context? Note File sharing or hoarding files not related to the site aren’t allowed in this hosting.

Thank you for your reply! Yes, I’m aware on how to install manually, but thought I’d try and find out why the plugins weren’t installed as they should (without going into File Manager / FTP / Control Panel). Whether the plugins were faulty or was there some server setting restriction on the free plan that prevents some scripts from executing.

File Upload feature: pretty wide range of applications actually, it’s strange that you would mention “file sharing” or “hoarding files” so specifically - it sounds accusatory. I’m just looking to build a site to accept document/manuscript submissions for purposes of reviewing before publishing.

Installations of big plugins can fail because of file size limits and script execution time limits. Those are not blocks on specific scripts, but rather a general block on scripts which stress the servers.

Thank you for the response

Caldera forms is a fairly useful and popular WP plugin, seems to be a shame not being able to install it normally.
