abort class-pclzip.php : Missing zlib extensions

[SergeyBiryukov]

Hi there, welcome to WordPress Trac! Thanks for the report.

The "Missing zlib extensions" error message is displayed if the ​gzopen() PHP function is not available, which is a part of the ​zlib PHP extension. That extension is used as a fallback if the ​zip PHP extension is not available.

Please note that this Trac is used for enhancements and bug reporting for the WordPress core software, not for individual support questions. If you need help with your site, please try the ​support forums, or contact your hosting provider to enable the zip or zlib extension.

It's also worth noting that both zip and zlib are on the list of ​recommended PHP extensions that the Site Health component checks for:

• zip is marked as required.
• zlib is marked as optional, since it's only used as a fallback for zip.

It you go to Tools → Site Health and check out the results, that should give you an overview if any other recommended PHP extensions are missing on your server.

As there's been no movement to indicate this is a bug more so than a support request after this time, I'm closing the ticket.

Should it later turn out there is some kind of bug here, then it can be revisited at such a time, if not the support forums is the best venue for further assisatnce.
