Thanks for that tip… solved the problem for me…

Just to be clear:
1. Comment out line 127 in activation.php
2. Your dashboard comes back – deactivate W3TC
3. Remove the comments for line 127 so it is active again
4. Activate W3TC and you are back in business

For those even “newbier” code people (like me) use the symbols below to comment out the line 127 using a code editor through your Cpanel or FTP access. (Only use symbols within the brackets. Don’t include the brackets.)

At beginning of line 127 type: [/**]
Create a blank line 128 and type into it: [*/]

Your commented out line 127 code should look thus:
/** throw new FileOperationException($error, ‘read’, ‘file’, $path);
*/

Save file and complete Step 2 from list above.

To reactivate, remove the /** and the blank line with */ and resave the file again.

You should be back in business.
