You need to split the file and manually upload it using ftp, there is a file limit of 10MB, So unzip the files locally, and manually upload them into the plugins folder

After test installing a plugin, it looks like it’s still not fixed and still a big issue.

That means the file might be over 10MB. I read somewhere on the forums from Admin that it’s 10MB from my memory.

Try force installing plugins. Worked for me.

How to force install plugins:
First, go to app.infinityfree.net > Manage the account you want > File manager > unpack locally into a folder > get to the plugins folder > upload folder with plugin contents inside. Hope this helped.

Download the theme and plugin files. Upload the folders for the theme and the plugins to the respective folders under “wp-content”. I did this a few minutes ago and it works perfectly.

You’re welcome! I do have one thing to figure out still. The Site Health page mentions this “The required module, zlib, is not installed, or has been disabled.”. Is there any way to do something like installing this extension or enabling it manually? I feel it’s a dumb question coz that’s what this thread is all about. :sweat_smile:

It’s because iFastNet is down. Let me know if it creates an issue. Anyways, because iFastNet is down with zlib, it’s not able to recognize it. Hopefully it gets resolved soon.

I heavily recommend you reinstalling everything you’ve installed manually during the outage just to make sure.

ia this issue of zlib resolved yet ? Thanks

Oh alright! Nah, the installations are fine otherwise. Uploading folders works.

Not yet. Try installing a plugin. If it says anything about zlib, then it’s not fixed. If the installation through Wordpress was successful, then yes, and I need an eye exam, think I’m goin blind on issues.

Also if you haven’t already, check out how to safely force install plugins.

Thank you everyone for suggesting, helping, and all the other amazing things you done on this topic! :partying_face:

I never thought so many people used Wordpress on InfinityFree, and never expected the topic to get big!

Within the span of like two days, we’ve managed to get 290+ views! Insane! :metal:

Should I make a website/whatever on force-installing plugins, and a more detailed tutorial? Let me know by messaging me! (or just replying) :blush:

If you’re talking about updating the WP version, you can do so by downloading the latest WP fr,om wordpress.org and then use an FTP client to upload it to your website folder. I don’t know much. I’m just trying to help but that’s how I updated mine. You would probably have content as well so don’t know how will it work with that.
