Error when trying to access Admin Panel

Hello!

I am getting an error message when I try to log in to my WordPress Admin Panel (at sitename.com/wp-admin). This pops up whether I try to access it different ways, on computer or on phone. The issue is not the password.

Here is my error message:
“Warning: Declaration of Sbi\Helpers\PluginSilentUpgrader::download_package($package, $check_signatures = false) should be compatible with WP_Upgrader::download_package($package, $check_signatures = false, $hook_extra = Array) in /home/sarahvdi/public_html/wp-content/plugins/instagram-feed/inc/admin/PluginSilentUpgrader.php on line 24

Warning: Cannot modify header information – headers already sent by (output started at /home/sarahvdi/public_html/wp-content/plugins/instagram-feed/inc/admin/PluginSilentUpgrader.php:24) in /home/sarahvdi/public_html/wp-includes/pluggable.php on line 1296”

I would like to fix the problem, which might be a plugin or it says something about an Instagram feed…? However, since I can’t access my Admin Panel, I can’t figure out how to fix the problem. I don’t mind deleting any and all Instagram on my website (I don’t think I even added it, but maybe I forgot…?) I have a WordPress website hosted by Siteground. I do have access to my Cpanel on Siteground, just not my Admin Panel on WordPress.

More information on this issue:

I changed my WordPress password, but that didn’t change anything.
Also through my CPanel I made sure it has the current version of WordPress installed, but that didn’t change anything either.
I cleared my cookies and cache in my Chrome browser, again no effect.

I was trying to Google how to clear my cache on my WordPress website through my cPanel, but I haven’t figured out how to do that yet.

I would like to email or call or live chat with WordPress support of any kind, but that doesn’t seem to be available to me, unless I have a paid version of WordPress…

Also I am able to access WordPress on my phone through the WordPress app, and I am able to edit Posts and Pages, however when I try to click on Admin Panel, it just takes me to the same error message.

I am currently trying to set up an FTP on my Siteground so maybe I can fix this issue, but I haven’t completed that yet.

If anyone could help me with this issue that would be so awesome. Any and all help I would really, really appreciate it so much!

Peacefully,
Sarah
