### Help & Troubleshooting
- [Install the WPC Site Installer plugin](https://www.wpproconverter.com/help/install-wpc-installer): Step-by-step guide to installing the installer plugin on a fresh WordPress site. Covers the Plugins → Add New → Upload Plugin flow and the post-activation Site Installer menu.
- [Installer too large or managed-WordPress dashboard](https://www.wpproconverter.com/help/install-large-or-managed-host): How to install the WPC Site Installer when the installer ZIP (often a few hundred MB, because it bundles all media for an offline install) exceeds the host's plugin upload limit (typically 64–128 MB). Three routes: Option A — unzip locally and upload the wpc-site-installer/ folder into wp-content/plugins/ via cPanel File Manager (upload-then-extract bypasses the PHP limit); Option B — same via SFTP; Option C — ask the host to raise upload_max_filesize and post_max_size to 512M. Also covers managed-WordPress dashboards (Plesk WordPress Toolkit / InMotion portal, MainWP, ManageWP, GridPane): their "Install plugin" search queries a public catalog and errors with `Unable to find asset "wpc-site-installer"` for a private installer — use the dashboard's Upload Plugin option or the site's own wp-admin instead, and note no top-level parent site is required.
- ["The link you followed has expired" on plugin upload](https://www.wpproconverter.com/help/plugin-upload-link-expired): Why WordPress shows this misleading nonce error when uploading large plugin zips. Root cause is PHP upload limits (upload_max_filesize default 2M, post_max_size default 8M) silently truncating the POST body before WordPress can check the nonce. Fix is to raise upload_max_filesize and post_max_size to 256M and memory_limit to 512M via php.ini, host PHP settings panel, or Docker conf.d snippet. Also explains the other two causes of the same message (genuinely expired nonce > 24h, CSRF) and how to tell them apart.
- ["The uploaded file could not be moved to wp-content/uploads/YYYY/MM"](https://www.wpproconverter.com/help/uploads-folder-move-error): Why WordPress fails to move uploaded files into wp-content/uploads. Root cause is usually wp-content/uploads being owned by root (from a post-install step run as root), so the web-server user (www-data, apache, nginx) cannot create the year/month subfolder. Fix is chown -R www-data:www-data wp-content/uploads && chmod -R 775 wp-content/uploads. Explains why fresh installs are affected more than migrations, and flags SELinux/AppArmor as a rarer cause.
