I can't upload the e-signature plugin to WordPress but file size is too large.

File size upload limitations are usually related to a server configuration issue.

If you do not have access to the proper server files we have good news:

There is a third-party plugin called “Upload Larger Plugins”

I swear there’s a plugin for everything 🙂

Upload Larger Plugins

install this plugin and upload the “E-Signature” plugin using this plugin.
