I followed the instructions detailed here:
...it did not resolve the issue.
I have PHP8 installed on Windows 10 and there is no php_gd2.dll in the ext folder, yet it is referenced in the php.ini.
So, I copied php_gd2.dll from an earlier version of PHP and dropped it into to the PHP ext directory.
I stopped and restarted IIS, to no avail, and when I check http://localhost/phpinfo.php, it does not show any settings for GD, suggesting that it is not installed.
So, considering that the php.ini file references php_gd2.dll yet in the ext directory of the PHP folder it only has php_gd.dll, I edited the php.ini file to reference, instead, php_gd.dll and when I run http://localhost/phpinfo.php it now shows GD info and the WebAssist extension is back working again!
I can only assume that this is an error with installation of PHP8. It's referencing php_gd2.dll when in actual fact the file, in PHP8, is php_gd.dll.
However, I fear my troubles are not over yet as I'm now getting this...
PHP Warning: PHP Startup: Unable to load dynamic library 'php_xmlrpc.dll' (tried: C:\Program Files\PHP\v8.0\ext\php_xmlrpc.dll (The specified module could not be found), C:\Program Files\PHP\v8.0\ext\php_php_xmlrpc.dll.dll (The specified module could not be found)) in Unknown on line 0
PHP 8.0.0 (cli) (built: Nov 24 2020 22:02:58) ( NTS Visual C++ 2019 x64 )
THere is no php_xmlrpc.dll in the ext directory of the PHP8 install.
Teething problems with PHP8? Should I be reporting this kind of thing?
