If your website shows errors like “The uploaded file exceeds the upload_max_filesize directive in php.ini”, “Allowed memory size exhausted”, “Request Entity Too Large”, or uploads/updates fail with timeouts, increase the PHP limits for your domain in Plesk.

Open PHP settings for your domain

Log in to Plesk (via My.GARMTECH → your hosting service → Login to Plesk).
Go to Websites & Domains → your domain → PHP Settings.

Which limits to change

upload_max_filesize – maximum size of a single uploaded file.
post_max_size – maximum size of the whole request; must be equal to or higher than upload_max_filesize.
memory_limit – PHP memory limit (imports, WordPress updates, large plugins).
max_execution_time / max_input_time – script runtime limits (restores, imports).
max_input_vars – useful for large forms and page builders.

Recommended starting values (WordPress)

Copy and adjust to your needs:

upload_max_filesize = 128M
post_max_size = 128M
memory_limit = 256M
max_execution_time = 300
max_input_time = 300
max_input_vars = 5000

Click Apply (or OK) to save. Changes take effect within a minute.

Good to know

Plesk File Manager upload limit is separate. For very large files, upload via FTP‑SSL instead.
If the values are capped by the hosting plan, higher numbers will not apply – contact support or consider a plan upgrade.
Custom values can also be set per directory with .user.ini.
