Class “Memcache” Error

@catonebros

In short, you’re having this issue, because your webserver’s PHP is missing the memcache extension.

To correct the issue immediately, you can just delete the file

/web/htdocs/www.coconinopress.it/home/wp-content/object-cache.php

And then once you install Memcache server as well as PHP’s Memcache extension, only then you should restore that file.

Thank you for the answer.

Please could you explain me how to install Memcache server and PHP’s Memcache exstension? Sorry but I’m not expert with this.

Thank you again

If you haven’t yet installed these, I suggest you don’t try it out on your live server, and ask your system admin/server manager to get it done.

For the time being, just delete the file I mentioned earlier, WordPress can run without it. If you still want to get those things done yourself, I’ll need to know a few things first,

1. Which Operating system is installed on the server and its version?
2. Which version of PHP is installed?
3. Which webserver is installed on your server and its version?
4. Do you have root access to the server?

Once I have these, I’ll be able to tell you exactly what do to, to install get memcache working on the server

Yesterday I contacted my server hosting provider, I’m waiting for an answer.

If the process is too complicated I won’t do it but I’ll appreciate your help the same!

1. CentOS 7
2. PHP 7.2.26
3. Apache 2.4
4. No

Thank you

Sorry, but you don’t have root access, so you can’t install it yourself. You’ll have to wait for your hosting provider to get it installed or configured for your account.

I deleted the file and the website returns online!

I have a question.
Previously I built a website on wordpress.com and I made a backup using UpdraftPlus. Then I installed www.remarpro.com on a new host and a new domain. On this new website I was making the restore (with UpdraftPlus – Migrator) of all backup packages created before but the error came out.

The question is:
if I finish to restore the backup package “Database”, can I normally use the website?
Or am I forced to restore the file /web/htdocs/www.coconinopress.it/home/wp-content/object-cache.php after having installed Memcache?

Thank you

Glad to know that the site is up again ??

About Updraft backup, you should be able to restore database(just database, not files) without any issue. Even all files can be restored except that object-cache.php file.

Updraft backups are simply zip files(as far as I remember), so you should be able to extract them on your system, and then restore what you want to, instead of doing the whole restore through plugin.

I hope the issue is resolved, in which case, we should mark it as resolved.

If you need assistance with anything else, you can create another support topic.

Good news:
I’ve finished the database restore and the migration appears completed! Hurray!

The only one flaw is that Updraft seems to reject uploaded files that have been previously edited. Because I’ve downloaded “others” backup zip from the first site, deleted /web/htdocs/www.coconinopress.it/home/wp-content/object-cache.php file inside the zip and reuploaded it into the second site, but Updraft doesn’t recognize it.

By the way very, very, very thanks to you for helping, for the patience and for answering in no time. Thank you so much, Gagan!
