Admin area not working

[jonmoore80]

Hi,

Just installed processwire

when i log in to the admin area i get a little popup saying "Unknown error, please try again later"

navigation menus dont work correctly they disappear as soon as i move down to them, same result in firefox,ie and edge

theres no errors in my server logs and the only thing i can see in the browser console is getPreventDefault() is depreciated

ive turned debugging on in config.php but this appears to be of no help

thanks

Check whether you have anything echoed before the starting "html" tag (view source in the admin)

can you post your version; i'm assuming this is a fresh install and you are running the minimum requirements for Apache, MySQL and PHP?

I have this same error message after a new install, it loads the pages after logging in but any subsequent attempts will display that error. I tried Ryan's suggestion here of adding the construct method to the Wire class with no luck. Same error using Chrome and FF.

ProcessWire 2.7.2
PHP 5.5.9-1
mysql Ver 14.14 Distrib 5.5.47
Apache/2.4.7

Thanks

Install adrian's debugger module

http://modules.processwire.com/modules/tracy-debugger/

that'll show you a whole lot more what is going on.

I have the exact same problem that occured on a working production install in 2.6.8.

No way to display the pages tree.

I checked the ajax request url to get the pages list directly and it returns some HTML code instead of JSON datas.

Every admin links related to pages seems to malfunction also.

I'm pretty stuck here

edit: i upgraded to 2.7.2 and it works again ! but it is a little strange that a working prod suddenly messed up
