The front end of my site works normally. However I cannot log into the administrator back end. Last week I noticed the log in process took a long time; this week I get 500 connection timeout errors, and my connection timeout settings are set high, over 1 minute. There is nothing in the PHP logs to reveal what the problem is unfortunately, so I changed Joomla's configuration file to enable debugging and accessed the front page of my Joomla site and saw this error, which leads me to believe it is an AdminTools problem:
500 - JDatabaseMySQLi::query: 1054 - Unknown column 'keepurlparams' in 'field list' SQL=SELECT `source`,`keepurlparams` FROM `jos_admintools_redirects` WHERE (`dest` = '') OR (`dest` = '') AND `published` = '1' ORDER BY `ordering` DESC LIMIT 0, 1
I tried renaming the admintools plugin files directory but this did not make a difference. Any ideas please?
