Suddenly I cannot upload files to the file manager?

Permalink
I was just updating a clients website which is about 3 years old and have never had a problem with it. Now out of the blue I am unable to upload files to the File Manager?

I am running version 5.6.3.2

I get the following message:
------
An unknown error occurred while uploading the file. Please check that file uploads are enabled, and that your file does not exceed the size of the post_max_size or upload_max_filesize variables.

File Uploads: 1
Max Upload File Size: 64M
Post Max Size: 64
------

What could cause this problem?
The files I am trying to upload are not large and I have never had this error before.

Hope someone can shed some light on this.

Regards
Luke

I also have a problem uploading files. For me, it does not seem to matter the size of the file, none of them will upload.

Looks like your Post Max Size is set at 64 bytes instead of 64 Megabytes..
Take a look in your php.ini file (if you have access to it) the line that controls the Post Max Size should read. post_max_size = 64M
If you not have access to your php.ini file, contact your hosting company.

I got the issue sorted out by speaking to my web host. They did something at their end and it solved the issue straight away.

I use a UK based web host. UK Web Solutions Direct

https://ukwebsolutionsdirect.co.uk/uk-web-hosting.php...

I have been using them for a few years with many C5 sites and they have been great.

First you check the post_max_size of the server by using the function phpinfo().

You just upload a file by writing echo phpinfo(); in the root of the server and run it and check that what is the value of post_max_size.

Even simpler is to go to System & Settings/Environment information and look at the #php settings section at the bottom
