Is there a Plugin upgrade for WordPress 4.5.3

Same issue here. Wish I could help, but I’m looking for the same thing you are, either a way around or a fix.

I’ve recently developed a testing version that could fix this issue. Please download this testing version, manually update to that version, and try updating your theme again.

Let me know if this fixes your issue. Once I get enough testing feedback, I plan on releasing the updated version.

Just tried this version and this is the message I got when I tried to update my theme:

Warning: POST Content-Length of 11681416 bytes exceeds the limit of 8388608 bytes in Unknown on line 0

Are you sure you want to do this?

Please try again.

The error indicates that your server’s PHP configuration limits a form POST submission (the process used to install the supplied zip file on the site) to no more than 8 megabytes of data and that you supplied a zip file of 11 megabytes, thus the request was blocked.

If you are using a hosting company, you will need to ask them for help increasing the post_max_size value found in the php.ini file from the default 8 megabytes to something larger, such as 20 megabytes.

If this problem is happening on a local environment, you will need to make the changes yourself. You can find instructions for doing so on a WAMP installation here.

Note: The upload_max_filesize setting in the php.ini file can also restrict the size of the uploaded file. This value may also need to be increased.

Thanks for the follow up, Chris. I did update the PHP as suggested by the link, increasing max settings.

I thought that the theme update was going to work as it got past where it had previously, but then the following error message came up with a install denial:

Unpacking the package…
Installing the theme…
Destination folder already exists. C:/wamp64/www/STP/wp-content/themes/*filename*/

Theme install failed.

Any ideas? I’ll admit that I am new to working with WordPress and themes. I had at least followed the suggestion of the theme provider to work in a Child version of the theme so that installing updates would not break my current work. So I would have assumed that since I was updating a theme, of course the destination folder SHOULD already exist. Not sure why that would be an error.
