I just installed October CMS on my hosting platform via cPanel's Softaculous utility. I do not believe installation method has anything to do with my errors but mentioning it just in case I am wrong. October CMS Version: 1.0.458 Sever PHP Version: 7.3.3
After installing in the designated directory it is showing "HTTP 500" generic error so I checked the error log. Following error was being shown
"[28-Sep-2019 11:09:04 Etc/GMT] PHP Parse error: syntax error, unexpected '[', expecting ')' in /home/XYZ/public_html/XYZ/vendor/october/rain/src/Support/helpers.php on line 149"
There is absolutely no online resource which describes occurance of such an error and possible solution. So I opened the helper.php to look at line 149. The code on this line was,
$query = str_replace(['%', '?'], ['%%', '%s'], $query);
Now there is nothing seemingly wrong with this line but I thought may be the "str_replace" function is not able to understand the array arguments. So I removed the array arguments and wrote it two times like
$query = str_replace('%', '%%', $query);
$query = str_replace('?', '%s', $query);
Now the error on this line disappears but a new error appears on another line as follows
PHP Parse error: syntax error, unexpected '[' in /home/XYZ/public_html/XYZ/vendor/october/rain/src/Support/helpers.php on line 238
The code on this line is
function trans($id = null, $parameters = [], $domain = 'messages', $locale = null)
Now here I am not sure if removing brackets would make everything alright. Why should such strange errors appears? Can someone help?
