After login in as administrator in webtrees version 2.0.13 i get the following message at the top of page
Error "GuzzleHttp requires cURL, the allow_url_fopen ini setting, or a custom HTTP handler."
Also there is no access to any of the admin tasks.
When i select control panel i receive a page of errors.
Refer to attached image.
I had a previous version 1.7 of Webtrees that was working.
I then updated to version 2.0.16 just now and once i discovered these errors i tried to reinstate the older backup copy. but could only reinstate version 2.0.13. After checking my server there is no previous backups of version 1.7 available.
I am lost and any help would be greatly appreciated.
